摘要
针对电网中广泛使用的CVT进行实时故障在线监测,重点分析了CVT故障引起电压测量值的变化情况,进而归纳出以电网实时监控系统中电压测量值的变化率为判据进行故障在线监测的方法,并通过故障案例验证了该方法的有效性.
The authors of this paper introduce some methods of detecting the fault of CVT. The recommended method is to use the voltage waveform to detect the fault of CVT. Through a typical case, the authors demon- strate that this method is useful to the online monitoring for the CVT.
