Abstract :
Metering accuracy coupling capacitor voltage transformers (CCVTs) are installed permanently in 230-500 kV substations and must be calibrated in place. Several years ago, the National Bureau of Standards (NBS) developed a field calibration system, with uncertainties of ±0.1% and ±0.3 milliradian.
