• Subcommittee A - Cable Construction and Design - Wednesday, November 11, 2009, 8:00 AM - 12:00 PM
  • 8:00 – 8:20 AM - Subcommittee Business/Announcements
  • 8:20 - 8:45 AM -  “Water Diffusion in Wet Designed High Voltage Polymer Cables”, Sverre Hvidsten, SINTEF Energy Research, NORWAY
    Abstract: Water treeing is considered to be the major aging mechanism in polymeric medium voltage cables. Water trees can be initiated if the relative humidity in the insulation is above a critical value, typically 70 %. A method for postponing the initiation of water trees in wet cable systems is therefore to reduce the amount of water entering the electrical insulation. This could be done by careful selection of outer jacket (barrier) materials with advantageous water permeability and solubility characteristics. The humidity levels could be kept low by combining an outer jacket having low water permeability with a layer of a material that has a high water absorption capacity. Results from numerical calculations of water ingress into the cable system are presented for combinations of different outer jacket materials and temperatures in the insulation system. The main finding from the calculations is that it is possible to maintain a low relative humidity in the electrical insulation for a long time even by using wet cable designs.
  • 8:45 - 9:10 AM - “High Frequency Signal Propagation in Tape Shielded Solid Dielectric Power Cable”, Jim (Jun) Guo, Steven Boggs, Institute of Material Science, University of Connecticut, Storrs, CT; Nelson Hall, Rick Stagi, Utilx Corporation, Kent WA
    Abstract: It has frequently been observed that very aged cables of copper shielded construction often have unusual signal propagation characteristics compared with new, tape shielded cables or cables with neutral wires. With age, the tape sheath becomes tarnished affecting the contact between the tape laps. The worst case occurs when the tape laps are non-conducting, so that the current path on the sheath no longer resembles a metallic cylinder, but instead is more realistically modeled as a coil. As the sheath current spirals down the coil it generates significant axial magnetic field, which increases cable inductance and thus affects the signal propagation velocity, cable characteristic impedance and high frequency attenuation. The field also induces eddy current in the cable conductor which contributes more loss in high frequency signal propagation. This paper discusses the effects of spiraling sheath current on cable inductance and high frequency signal propagation properties, i.e., propagation velocity, characteristic impedance, and attenuation.
  • 9:10 - 9:35 AM - “Considerations for Injecting Cables with High Conductor Temperature”, Glen J. Bertini, Norman E. Keitges, and Gary A. Vincent, Novinium, Inc
    Abstract: The first generation of injection technology was intended for lightly loaded cables in cool soils. Attempts to utilize the first generation approach for more heavily loaded cables in warmer climates, particularly feeder cables, have not proven reliable. Previously identified issues namely super saturation, over saturation, asymmetrical penetration profiles, and aluminum corrosion are reviewed. A previously unidentified failure cause is described. A new generation of injection technology is described that addresses all of the identified post-injection performance issues.
  • 9:35 - 10:00 AM - “Effect of Chemical Impurities in PE on Creation of Traps and Hopping States”, Ahmed Huzayyin, Steven Boggs, Department of Electrical and Computer Engineering, University of Toronto, Toronto, Ontario, Canada and Ramamurthy Ramprasad, Steven Boggs, Institute of Materials Science, University of Connecticut, Storrs, CT
    Abstract: Computational quantum mechanics (density functional theory) has been used to investigate the effect of chemical impurities, such as vinyl, carbonyl, double bonds, and conjugated double bonds, on the creation of traps and hopping states in polyethylene. A core-shell model was provides a much better approximation of the amorphous state than usual models based crystalline PE. This led to the discovery that chemical impurities create both deep traps, in the range of 0.9 to 2 eV, but also create shallow traps or hopping sites in the range of 0.4 eV below the conduction band minimum. For the most part, these shallow traps are caused by distortion of the chemical bonds adjacent to the impurity. Plots of the electron density show that some impurities, such as carbonyl, cause appreciable overlap of the wave function (electron density) between the impurity and adjacent PE chains which can promote conduction.
  • 10:00 - 10:30 AM - Break
  • 10:30 - 10:55 AM - “Accelerated Cable Life Test (ACLT) Results with Reduced Insulation Wall Thicknesses – An UpDate”, John T. Smith, III, General Cable Corporation
    Abstract: The IEEE P1407 Draft Guide for Accelerated Aging Tests for Medium-Voltage (5 kV – 35 kV) Extruded Electric Power Cables Using Water-Filled Tanks recommends that maximum conductor shield test stresses be limited to 300 V/mil (12/kV/mm). A previous presentation showing preliminary results of TRXLPE insulated cables at test stresses far exceeding the recommended test stress levels of P1407 at 525 V/mil (25kV/mm) showed ACLT life of 3 – 4X that of full-size wall cables. This update will show final ACLT results of reduced wall cables tested at typical accelerated stresses (200V/mil, 8kV/mm) used in testing full-size wall cables. The results indicate that currently available TRXLPE insulations in a reduced wall cable design have the capability of providing longer life than full-size wall cables. Preliminary results will show that for currently commercially available conductor shields and tree-retardant crosslinked (TRXLPE) insulation systems, characteristic life and testing times are  3X that of full-size (175-mil) insulation wall cables at the typical maximum conductor shield test stress of 200 V/mil (8kV/mm). This result is demonstrated in two (2) different ACLT protocols. The presentation will also provide information on the effects of various preconditioning protocols (to remove the crosslinking by-products acetophenone, dimethylbenzylalcohol, alpha-methylstyrene) on ACLT life performance of reduced wall TRXLPE cables.  POSTPONED UNTIL SPRING 2010
  • 10:55 - 11:20 AM - “Effect of Controlled Amounts of Moisture on the Performance of Paper-Insulated Lead Sheath Cables (PILC)”, Bogdan Fryszczyn, Cable Technology Laboratories
    Abstract: Failure analysis of Paper Insulated Lead Covered (PILC) cables indicates that the ingress of moisture into the cable insulation is the major reason for its failure. Once the impermeability of the lead sheath is breached, water will penetrate the insulation. The water reduces dielectric strength and insulation resistance and increases its dielectric loss. Since the dielectric loss increases with temperature, the majority of failures occur during the summer when the current loading and cable temperature are the highest. At present, high voltage direct current (dc) or very low frequency (VLF) voltage maintenance tests are used by utilities to remove degraded cables from service, prior to the heavy load summer periods. It is the experience that even after such tests are made, a number of failures take place during heat waves. Therefore, it is of interest to quantify the level of moisture that makes the cable unsuitable for further service. In this project, the insulation moisture content level, above which cables are considered unsuitable for further service by dc maintenance testing, was established and designated as “DC Critical Moisture Content”. Similarly, maintenance testing “VLF Critical Moisture Content” was established. “AC Critical Moisture Content” was also found. The three critical moisture contents (dc, VLF and ac) are compared. The results of the study call for a change in the IEEE 400.2 Standard titled “IEEE Guide for Field Testing of Shielded Power Systems Using Very Low Frequency (VLF)” recommended maintenance test values.
  • 11:20 - 11:45 AM - “Advanced Design of Metal Laminated Coverings, Overview of a 3-year Study by CIGRE”, Pierre Mirebeau, Nexans High Voltage Extruded Cable Systems, NEXANS FRANCE
    Abstract: CIGRE has set up a working group for a period of 3 years to revise the: "Guidelines for tests on high voltage cables with extruded insulation and laminated protective coverings" WG 21.14 published in ELECTRA No. 141 [1] in April 1992, as numerous technical improvements appeared on laminated coverings since 1992, in parallel with service experience.

  • 10:10am – 10 30am Business Meeting
  • 10:30am – 11:00am Presentation 1 Title: Test Program of Copper and Aluminum Electrical Connectors under Severe Ageing Conditions
    Presenter: Vern L. Buchholz
    Abstract: Crimped or mechanically bolted connectors are commonly used for terminating and joining electrical power cables used for all forms of electrical systems. Many of these systems, including renewable energy and industrial facilities, must operate in harsh environments and under severe conditions. These connectors, although simple and inexpensive, can be the weak link in a system, and a connector failure is often the cause of a long and costly outage. In this presentation the performance of copper and aluminum connectors tested by accelerated aging under corrosive environmental conditions will be discussed. The testing consisted of 2000 hours of cyclic salt fog environmental exposure, in conjunction with periodic electrical current burst testing. The connectors were evaluated by comparing the change in resistance of the test samples as the test progressed. The test procedures, results and conclusions will be presented.

  • 12:00pm – 12:30 pm Open Discussion on “Problems and Issues Associated with Replacement of Old Terminations and Joints”
• Subcommittee C - Cable Systems - Tuesday, November 10, 2009, 8:00 AM - 12:00 PM
  • 8:00 - 8:10 am Chairman’s Opening Remarks, by Ted Nishioka, Arizona Public Service
  • 8:10 - 8:45 am Systems for Continuous Monitoring of Pressure, Temperature, Level and Flow on Pipe-Type Cable Installations Using Industrial Wireless Technology, by Ricardo Chavez, Vanguard Controls, Inc
    Abstract: Monitoring pressure in real time is one of the critical parameters in a pipe-type cable installation and proves to be challenging by traditional methods, whether it is done manually or with pressure transmitters. Common problems with hard-wired pressure transmitters around the substation environment include noisy signals caused by high EMF, and damage to the transmitters themselves due to lightning, switching surges, and ground loops. Measuring other parameters such as dielectric fluid tank level, flow, and temperatures within the substation all involve similar challenges.
    The wireless transmission technology known as, "frequency hopping spread spectrum" has proven successful in a wide range of applications for monitoring pressure, level, flow and temperature at different substations. Other applications include the dynamic feeder rating calculation using temperature and current data on solid dielectric cables. Transmission distances of 2500 feet between the field units and receiver station are easily achievable, and longer distances can be accommodated using high gain antennas. Steel structures and other obstructions in the transmission path do not compromise signal strength.
    The wireless field transmitters provide a, "true wireless" solution, since the sensors run on integral lithium batteries designed to last 5-7 years at a data transmission interval of 30 seconds. The monitoring system built around the wireless network is designed to provide real time diagnostics of the system, including battery status and connectivity status. Faster scan rates can be automatically triggered by alarm events, and real-time logging and trending provide useful historical information. All variables can be easily viewed on a color TFT touch screen display with Ethernet capabilities for LAN and/or web connectivity. Data can also be moved wirelessly to additional control locations.

  • 10:15 - 10:50 am Progress Energy’s Bartow NE Project-230kV 5000 kcmil Copper Conductor XLPE Cable Installation, by Paul Jakob, Progress Energy, Jerry Johnson, Power Engineers, S.W. Jue, Taihan Electric
    Abstract: The expansion of the Bartow Power Plant required the installation of three additional 230kV underground circuits and one future circuit connecting the power plant and the Northeast Substation. In Phase I the Team determined the best cable system for the project through investigation and comparison of high pressurize fluid-filled and solid dielectric cable systems. In phase II the Team provided complete engineering for installation of the circuits with selected 230kV XLPE systems. The project is over four miles in length and consists of four circuits with 5,000 kcmil copper conductors - the largest in the United States at the time of installation. The work scope included survey coordination, layout, utility coordination, permit drawings and system design, including design of substation structures and concrete duct bank. Installation involved standard jack and bore, micro tunneling, and a double 42 - inch diameter, 1,700 -foot horizontal directional drill.
  • 10:50 - 11:30 am Remote Transformer Diagnostics: APS’ Transformer Oil Analysis and Notification (TOAN) System, by Don Lamontagne, Arizona Public Service
    Abstract: Since early 2005, Arizona Public Service Company has been developing an analysis and notification tool for power transformer insulating oil dissolved gas analysis (DGA). Known as TOAN (Transformer Oil Analysis and Notification), the system gathers data from one-hundred and thirty-eight on-line DGA monitors. With the advent of multi-gas, on-line transformer Dissolved Gas Analysis (DGA) monitors, a large amount of data is available to determine true gassing rates of individual gases within power transformers. Prior to the existence of these monitors, which appeared in the late 1990s, electric utility power transformers were sampled manually. The frequency of regular manual sampling may be as often as quarterly for critical transformers (e.g., power plant Generator Step-Up transformers) and as little as annually or bi-annually for less critical transformers. Many transformers have load dependent internal faults and exhibit cyclic gassing rates due to cyclic loading of the transformer. As a result, manual samples may not occur at intervals that are "in phase" with previous samples. This leads to distortions and inaccurate measurements of gassing rates. TOAN uses harmonic regression analysis and piecewise linear approximation to stabilize the measured gassing rates and to quickly determine and report changes to the measured gassing rates, respectively. The harmonic regression equation can better predict future values of dissolved gasses, and when combined with evolving CO & CO 2 versus degree of polymerization prediction models it is a very powerful asset management tool. APS was awarded the Edison Electric Institute's 2008 Edison Award for TOAN. The Edison Award has been given annually since 1922 to a U.S. shareholder-owned and an international affiliate for "distinguished leadership, innovation, and contribution to the advancement of the electric industry for the benefit of all."

  • 2:45 - 3:10 PM - Fire Calorimetry - A Fire Science Topic for Future IEEE Fire Standards, by Javier Trevino/Intertek
    Abstract: Heat Release Rate is the most important parameter that defines the intensity of a real fire. The science that allows one to measure Heat Release Rate is Oxygen Depletion Calorimetry - or Fire Calorimetry. This technology has existed for over 20 years as a standardized test apparatus and is used to test items such as upholstered furniture, mattresses, interior room finishes, plenum mounted devices, pipe insulation, insulated garage doors, and decorative foam objects used in retail spaces. In each of these cases, specific Maximum Heat Release Rate thresholds have been established. However, in the world of tightly packed cable bundles, this fire measurement device is rarely used for regulatory purposes. The science on which the Heat Release parameter is based is explained with an emphasis on possible applications to the wire/cable industry.

  • 2:20 - 2:45 - 10 kV XLPE Cables to be Operating at 20 kV, a Challenging Process of Upgrading, Willem Boone , KEMA
    A utility in the NL wants to investigate if existing 10 kV XLPE cables in the distribution network can be operating safely at 20 kV. KEMA was asked to recommend what different steps have to be taken to make the decision well-founded. The following steps are proposed:
    1. Theoretical study: To consider electrical aging phenomena and related remaining life
    2. Laboratory testing: To perform type testing on new 10 kV XLPE cable based on 20 kV requirements
    3. Long term field testing: To perform long term field test on 100m length together with accessories, including diagnostic testing
    4 Criteria: To develop criteria to justify the decision to be taken.
    In the presentation the different steps will be evaluated in more detail. As this project is still in the preparatory phase, a discussion with the audience on the proposed way to obtain upgrading, is appreciated.
  • 2:45 - 3:10 - Phase Resolved Online PD Detection for Cable Systems, Oscar E. Morel, Nagu N. Srinivas UtilX Corporation, U.S.A.
    An online partial discharge (PD) detection technique applicable to cable systems will be described in this paper. PD signals can be detected and located by the use of high frequency narrowband detectors with coupling sensors; in conjunction with the natural attenuation of power cables. Pattern recognition of power frequency synchronized time domain traces can be utilized to identify the type of PD sources. For cables with metallic wire screens, PD sources can be detected at distances over 300 m from the source, however, the increased signal attenuation of solid shielded cables (PILC) somewhat reduces this measuring range. This technology can also be applied to determine the condition of joints and terminations, and other equipment directly connected to the cable. The suitability and the sensitivity of the VHF technique has been confirmed with other PD detecting techniques utilizing standard air gaps and cavity models under laboratory controlled conditions.
  • 3:10 - 3:35 - Use of VLF Methods in Utility Reliability Programs - Basic Concepts
  • Break - 15 Minutes
  • 3:50 - 4:15 - The development of an Assetmanagement discussion model for 50kV SCFF cable circuits,  Aloys Bun (Liander Assetmanagement), Kelvin Hooft van Huisduijnen (Delft University), Frank de Vries (Liandon)
    In our utility (Alliander), about 1500 miles of 50kV oil filled (SCFF) cables are installed. Most of these cables are about 40-50 years old. Decision processes about the operation, maintenance and replacement of these underground cable circuits are important asset management (AM) issues. Depending on the AM goals different strategies can be used.
    To support our AM department research will be done to propose a method/tool to support the evaluation process. In particular based on an analysis of different information about e.g. asset construction, load history and future planning, maintenance and failure history, actual condition; different AM scenarios will be proposed. Based on an inventory, analysis and extraction of information (related to network components, infrastructure, maintenance, operation, actual condition, history, planning) as relevant to life time management of underground transmission connections this presentation discuses a proposal of a model for decision support in operation, maintenance and replacement of service aged connections.

    Typical defects can be introduced in cable systems during installation in the field, if jointing of the cable accessories is performed incorrectly. The physical definition of these defects, the PD occurrence and the detectability based on different PD detection methods and different voltage energizing are very important. The systematic relation between PD detection methods, testing voltages and PD occurrence will be discussed from the point of view of on-site PD detection for after-laying test of HV cable accessories. Based on an inventory of most typical defects that can occur during installation process of HV cable accessories and its electric field enhancement which can result in PD activities three different installation defects will be investigated. Applying continuous and damped AC voltages and conventional and unconventional PD detection methods the test condition will be fixed and the estimation of PD sensitivity in pC for non-conventional method by using sensitivity and performance check for certain defect will be investigated.
  • 4:40 - 5:05 - Significance of Field Tests on XLPE Cables K. Abdolall & M. Stephens, Powertech Labs Inc. D. Tarampi, BC Hydro
    Condition assessment tests of in-service XLPE cables include the evaluation of the cable insulation and the accessories. Some of the major causes of failures for such cables are natural aging of the materials, and water related degradation. Several field techniques are presently used to evaluate the condition of in-service cables. Laboratory tests are also carried out on sections of cable and accessories removed from service to determine the condition of the cable run. A comprehensive study was carried out to validate the effectiveness of some of the test techniques used in the field and improve the predictive capability of the test protocols used. The tests consisted of LIpA Tests in the field, and laboratory tests including 60Hz tan delta, ac breakdown , and microscopic and water tree analysis on cable runs removed from service. The results are discussed in terms of the effectiveness of the techniques used to identify defective splices or portion of the cables in long cable runs.
  • 5:05 - 5:30 - Demystifying Sensitivity Assessment & Magnitude Calibration for Locating PD in Cable Systems, Steffen Ziegler, Andy Szatkowski, Benjamin Lanz - IMCORP
    Two important procedures used for determining the reliability of partial discharge (PD) diagnostic tests results are sensitivity assessment and magnitude calibration. These procedures have been used by the industry since the 1960's to assure that test results indicating the existence or absence of PD are repeatable and conform to performance expectations defined by international standards. International standards dictate procedures to be used in electromagnetically shielded test facilities in cable and cable accessory factories. As a part of these standardized procedures, there are a series of required steps which provide assurance that known test constraints, such as noise, superposition, and attenuation do not adversely impact the test results. These constraints, along with several other issues have been reported to cause significant measurement error in many of the PD technologies currently being utilized in the field. Since 2002, one PD diagnostic technology, in its fourth generation of development, has demonstrated the ability to consistently and adequately compensate for field constraints in over 30,000 tests. This technology provides cable system owners with the assurance that the test results are reliable and can meet and even exceed the expectations of the new product quality assurance tests performed in factories today.
