Coupling Capacitor Voltage Transformers Models and Impacts on Electric Power Systems: A Review

Coupling capacitor voltage transformers (CCVTs) are the predominant devices used in high voltage systems to provide scaled-down voltage signals for metering, protection, and control devices. The performances of these devices are subject to errors due to the transient behavior of CCVTs, so that the u...
