43、C Electric Machinery. Partial discharge (PD) measurements have been made on the windings of ac electric machinery for over 40 years. The electrical insulation of these windings may be prone to PD activity as a result of internal delaminations and of surface or slot discharge. These kinds of PD activ
44、ity, when the machine is in normal operation, can result in significant deterioration over a period of time. Experience has indicated that PD measurements can be useful for assessing the condition of complete windings as well as of individual formwound coils and bars. This guide provides a review of
45、 the nature of PD in machine windings, how it can be measured under both off-line and on-line conditions, how it can be measured for individual form-wound coils or bars, and the significance and limitations of the measured values. IEC 60505 (2004-10)adefines the various factors that influence the pe
46、rformance of electrical insulation systems. These are the thermal, electrical, environmental, and mechanical stress factors. Stator winding insulation systems of ac electric machinery experience thermal, electrical, mechanical, and environmental stresses during operation. These stresses, individuall
47、y or in combination, will age the insulation system and may lead to delamination of the groundwall insulation, abrasion of the outer semiconducting (Faraday) shield, loosening of the wedging system, and other potential deterioration mechanisms. Sometimes, as a result of the initial manufacturing pro
48、cess, or because of the subsequent aging, PDs may occur adjacent to the high voltage conductor, in the internal voids of the groundwall, on the outer surface of the coil/bar in the slot, or in the endwinding region. These various PD sites have the potential to cause deterioration to a greater or les
49、ser extent and, in some cases, may ultimately result in an in-service failure. The number, magnitude, and polarity of these PDs can be a direct indication of the condition of the insulation system. However, the trend of these parameters over time is frequently most valuable. Care must be taken that the effects of operating and environmental conditions and test procedures are considered. aIEC publications are available from the International Electrotechnical Commission (http:/www.iec.ch/).
