WG F10D Diagnostic Testing of Cable Joints and Terminations

• Return to Subcommittee F - Field Testing and Diagnostics

Officers:

• Chairman - Harry Orton, OCEI, h.orton@ieee.org
• Vice Chairman - Grace Jiang, 3M, gjiang@mmm.com

Purpose:

To investigate present and developing proactive diagnostic techniques for the evaluation of power cable joints and terminations on newly installed and in-service transmission and distribution cable systems. This task group will focus on field data and results rather than diagnostic methodologies.

Mission:

The scope of the discussion group is to evaluate the diagnostic data obtained on cable accessories not the methodologies of obtaining the data.

• A message from DG Chair, Harry Orton, October 6, 2010:
  Over the last two meetings we have been discussing a project by VDE that closely supports the goals of DG F10.  VDE has created an online database of PD measurements on medium voltage cable systems that have been validated by visual inspections of the located PD faults.  This is a publically available knowledgebase, that is supported through our submissions.  Please visit the knowledgebase at http://www.vde-kabeldatenbank.de/main/view.php?language=English and submit any test result you can.
  The use of onsite PD measuring systems is more and more common to detect and locate PD faults to prevent service failures and loss of power supply. To perform a PD measurement is quite easy, but the interpretation of the results rises often more questions and makes the decision for replace or repair difficult. The increasing number of joint failures prepared in the past 15 years was an initial point to establish a VDE-working group to collect and share experiences of onsite PD measurements. More than 30 German utilities and several manufactures of pd measuring equipment are members of the working group. The outcome of this work is a WEB database, to collect in a clear structure the most important pd parameter of field measurements and the results of visual inspections of the located pd faults. The online presentation of the database will show the ease of use and the way of evaluation of pd measurements and severity estimation of the specific pd faults. Because the ignition of PD in a defect depends from the type of excitation voltage the database is structured accordingly. The data collection in the database should be not limited on German utility and industry networks, but can be also used for worldwide input and use for interpretation of onsite pd measurements.
