New IEEE Standard – Inactive – Withdrawn. This guide defines methods of measuring partial discharges that may occur in energized power switchgear apparatus in flaws, voids, and interfaces of non-self restoring insulation that may then result in dielectric failure of the switchgear. Guidance on instrumentation and calibration technique is also given.<\/p>\n
