摘要
三倍频感应耐压试验可检测电磁式电压互感器的绝缘情况。通过应用变频电源,采用补偿电感、改变互感器变比等方式,改进了试验方法,降低了试验的难度。
Tripler induction voltage test can detect electromagnetic voltage transformer insulation.Through the application of variable frequency power supply,the use of compensating inductance,changing transformer ratio,etc.,test methods were improved to reduce the difficulty of the test.
