摘要
变压器在现场进行局部放电试验前应根据被试变压器的结线组别、容量、电压、变比来科学地选用试验结线，合理地估算出有功和无功功率，尤其是无功功率，否则将会给现场试验带来很大不便。本文叙述了计算方法、现场的几种试验接线和局部放电的测量方法。
Before carrying out the field partial discharge test of transformer， the testing scheme should be carefully sefected accordng to the connection， capacity， ratio of transformation and the voltage class of tested transformer，the active and reactive power for testing should be rationally estimated． In this paper the cafeufation method of estimating power consumption， especially the reactive power consumption， Ii the test is described， some field test scheme and the measuring method for partial discharge are presented．
