Abstract :
In recent years, the coupling capacitor voltage transformer (CCVT) has come into wide use for 0.3% accuracy extra-high voltage (EHV) revenue metering in interties between utilities. Considerable user experience raised doubts as to its adequacy for this application and suggested the need for periodic calibration. Since the CCVT is permanently installed, this calibration must be done on-site.
