scope:

This guide describes VLF withstand and other diagnostic tests and the measurements that are performed in the field on service-aged shielded medium and high-voltage cables rated 5 kV through 69 kV with extruded and laminated insulation. VLF test methods utilize ac signals at frequencies less than 1 Hz. The most commonly used, commercially 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.

Purpose

This guide is intended to provide troubleshooting and testing personnel with information to test shielded medium- and high-voltage cable systems rated 5 kV through 69 kV using VLF ac techniques.
