Full Description

Scope

This guide describes the test procedure for the electrical measurement of partial discharges (PDs) occurring in Bushings and Instruments Transformers during AC and DC dielectric tests. General principles of PD measurements, including the narrowband method, are covered in IEC 60270 "High-voltage test techniques - Partial discharge measurements".

Purpose

Measurement of partial discharges in bushings and instrument transformers following an applied potential test should preferably be made on the basis of measurement of the apparent charge. Relevant measuring systems are classified as wideband or narrowband systems. Both principles are recognized and widely used. Without giving preference to one or the otherre, this document describes the measurement circuits related to the wideband method.

Abstract

New IEEE Standard - Active - Draft.This guide describes the test procedure for electrical measurement of partial discharges (PD) in bushings and instrument transformers using wide-band measuring instruments for the evaluation of the apparent charge level of PD occurring under AC and DC test voltages.
