CVT
Capacitive Voltage Transformer (CVT) Definition: The capacitive voltage transformer step-down the high voltage input signals and provide the low voltage signals which can easily measure through the measuring instrument. The Capacitive voltage transformer (CVT) is also called capacitive potential transformer The capacitive potential divider, inductive element and the auxiliary transformer are the three main parts of the capacitive potential transformer. What is the need of CVT? For measuring high voltage (above 100kV) the high insulated transformer is required. The highly insulated transformer is quite expensive as compared to the normal transformer. For reducing the cost, the capacitive potential transformer is used in the system. The CVT is cheap, and their performance is not much inferior to the highly insulated transformer. Capacitive Voltage Transformer Working The capacitive potential divider is used in combination with the auxiliary transf...
