F03W - Very Low Frequency Testing in the Field - IEEE 400.2 (P400.2)

• Return to Subcommittee F - Field Testing and Diagnostics

Officers:

• Chairman - John Densley, j.densley@ieee.org
• Vice Chairman - Tim Hayden, National Grid

Purpose:

This guide is intended to provide troubleshooting and testing personnel with information to test shielded medium voltage cable systems using very low frequency techniques.

Mission:

This guide describes very low frequency (VLF) withstand and diagnostic tests and
the measurements that are performed in the field on service-aged shielded medium
voltage cables with extruded and laminated dielectric insulation. VLF test methods utilize
ac signals at frequencies less than 1 Hz. The most commonly used, commerically
available, VLF test frequency is 0.1 Hz. Whenever possible, cable systems are treated in
a similar manner to individual cables. Tables are included of the recommended test
voltage levels for installation, acceptance and maintenance tests.
