摘　　要：本文提出一种带输电线路进行一次升流和对厂内变压器进行短路试验检查相应TA,TV回路的方法,并进行短路计算和现场试验。试验方法简单、可靠,既能够检验一次系统的接线,又能够全面地检查二次电流电压回路,解决了新建电厂带负荷校验保护极性的难题。A method of increasing current value of transmission line and checking TA, TV circuit for transformer of service station by short-circuit test is proposed in the paper. Accordingly short-circuit calculation and field test are conducted. The test method is simple and reliable. The wiring of primary system and the secondary loop can be examined comprehensively which solve the problem of polarity protection checking with load in new-builted power plant.
