Guide for Field Testing of Shielded Power Cable Systems Rated 5 kV and Above with Damped Alternating Current (DAC) Voltage
|Publication Date:||30 October 2015|
This guide presents the practices and procedures for testing and diagnosis of shielded power cable systems rated 5 kV and above using DAC voltages. It applies to all types of power cable systems that are intended for the transmission or distribution of electric power. The tabulated test levels assume that the cable systems have an effectively grounded neutral system or a grounded metallic shield.
The purpose of this guide is to provide uniform practices and procedures for performing (DAC) voltage off-line tests on installed shielded power cable systems in the field and to provide guidelines for evaluation of the test results. As at present certain test parameters and procedures require further study and clarification, this guide provides a starting point that can be grown and improved with time as more experience is gathered from the field and analyzed.
