The detection of partial discharges occurring in the insulation of dry-type transformers or their components and the measurement of the associated apparent charge at the terminals when the alternating test voltage is applied are covered. The wideband method is used. The detection system and calibrator characteristics are described, and the test procedures are established.

PC57.124
Recommended Practice for the Detection of Partial Discharge and the Measurement of Apparent Charge in Dry-Type Transformers
This recommended practice describes the test procedure for the detection and measurement by the wide-band apparent charge method of partial discharges (PDs) occurring in dry-type transformers during dielectric tests, where applicable.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
