The energy metering accuracy and relay protection reliability in power grid systems critically depends on the phase current measurement accuracy. Commonly manufactured electronic current transformers (ECT) may exhibit unacceptable errors during field operation. Our research platform targets to remotely monitor ECT’s errors caused by ambient temperature variation, load current, and adjacent phase interference...
The resistive shunt is generally used as a sensor in the high voltage direct current (HVDC) system. The high frequency alternating current has an impact on the performance of the shunt owing to the skin effect and proximity effect causing DC measuring errors and even leading to protective system false operation. The impact of skin and proximity effects on the squirrel cage shunt is discussed in the...
