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 use of CCVT digital models is essential for studying power systems in order to predict how the equipm...
