適用范圍：This standard applies to the measurement of partial discharges during tests with alternating voltage, but general terms, definitions and requirements are usually also applicable for measurement of partial discharges during tests with direct voltage. Some special characteristics of partial discharge measurements under direct voltage are given in a separate clause and necessary references are made throughout the text. This standard is intended principally as a general guide to the drafting of specifications for specific apparatus.Measurements of partial discharges are made for the following main purposes:— to verify that the test object does not exhibit partial discharges greater than a specified magnitude, at a specified voltage;— to determine the voltage amplitude at which partial discharges of a specified low magnitude commence with increasing voltage and cease with decreasing voltage;— to determine the magnitude of the specified discharge quantity at a specified voltage.
