This guide covers the diagnostic testing of new or service-aged installed shielded power cable systems, which include cable, joints, and terminations, using PD detection, measurement, and location. Partial discharge testing, which is a useful indicator of insulation degradation, may be carried out on-line or by means of an external voltage source. This guide does not include the testing of compressed gas insulated systems or continuous on-line monitoring at normal service voltage.
Purpose
This guide describes diagnostic methods capable of detecting and locating partial discharges from defects and damage in installed shielded power cable systems. The results of PD tests are used to assess the condition of cables and accessories.
Abstract
New IEEE Standard - Active.This guide covers the diagnostic testing of new or service-aged installed shielded power cable systems, which include cable, joints, and terminations, using partial discharge (PD) detection, measurement, and location. Partial discharge testing, which is a useful indicator of insulation degradation, may be carried out on-line or off-line by means of an external voltage source. This guide does not include the testing of compressed gas insulated systems or continuous on-line monitoring at normal service voltage.
