Description / Abstract:
This Recommended Practice applies to the detection of partial
discharges occurring in the insulation of electrical apparatus or
its components, and to the measurement of the associated apparent
charge at the terminals, when an alternating test voltage is
applied. Tests for partial discharges using direct voltage are
discussed in Appendix E.
This Recommended Practice is concerned with general principles
only. Where specific apparatus is covered by standards documents
that include corona detection and measurement procedures, those
standards should be followed.
