Describes a measurement of partial discharges during tests with alternating voltage. Special characteristics of partial discharge measurements under direct voltage are given. Intended as a general guide to the drafting of specifications for specific apparatus. Measurements of partial discharges are made 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, and to determine the magnitude of the specified discharge quantity at a specified voltage. Covers test circuits, calibration, and sources of disturbances.
