This Guide applies to the detection, measurement and interpretation of partial discharges (PD) occurring in or around the insulation of electrical apparatus or its components through phase resolved measurement of the associated apparent charge appearing at the terminals when an alternating voltage is applied. Topics addressed include: * information on basic discharge physics and material related defect discharge mechanisms, * basic principles of electrical PD calibration, detection, and measurement using the apparent charge method, * explanation and interpretation of phase resolved PD patterns associated with common insulation defects, * explanation and interpretation of the effects of time and voltage level (electric field stress) on PD behavior associated with common insulation defects, * tutorial information regarding the internal propagation of high frequency signals resulting from partial discharges occurring in high-voltage equipment, and the resulting impact on measurement sensitivity. While the information presented is generally applicable to measurements made both in the laboratory and in the field, a separate clause is included to offer guidance on special considerations and techniques that can be especially useful in noisy environments (e.g. field measurements). Where apparatus-specific testing procedures or requirements are involved, these shall be specified by the relevant Technical Committee.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
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No Superseded Standards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No Inactive-Withdrawn Standards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
