CCVT stands for coupling capacitor voltage transformer.

CCVT stands for coupling capacitor voltage transformer.

• A. coupling capacitor voltage transformer
• B. current capacitor voltage transformer
• C. coupling capacitor variable transformer
• D. current capacitor variable transformer

Answer: (A)

The concept tested is understanding what CCVT stands for and how the device works. CCVT, or coupling capacitor voltage transformer, describes a voltage-sensitive instrument that uses a network of coupling capacitors to feed a voltage transformer. The capacitor divider taps off a small, safe fraction of the high line voltage and couples it into the transformer, which then provides isolation and a downscaled voltage for relays and meters. This is all about measuring voltage, not current, and it isn’t a variable or adjustable transformer. That’s why the accurate expansion is coupling capacitor voltage transformer.
