Partial discharge measurements

This document establishes the fundamental principles and technical specifications for the measurement of partial discharges within electrical apparatus. It defines the procedures for connecting test circuits to the device under examination to ensure accurate detection and quantification of discharge phenomena occurring at insulation defects. The standard outlines the characteristics of necessary measurement equipment, including coupling devices and charge measuring instruments, emphasizing the importance of calibration and frequency response. It provides guidance on interpreting measurement results to assess the severity of insulation conditions without necessarily indicating the exact timing of its issuance or the originating committee. By offering a unified framework, it facilitates consistent testing methodologies across various voltage classes and equipment types. The guidelines focus on minimizing external interference and ensuring repeatability in laboratory and field environments. This foundational text serves as a reference for engineers and technicians involved in quality control, acceptance testing, and condition monitoring of high-voltage components, ensuring reliable assessment of dielectric integrity.
