Inductive Voltage Transformers (IVT) and Capacitive Voltage Transformers (CVT) are used to step down high voltage levels for measuring or monitoring purposes. They provide a safe and accurate way to measure voltage without exposing personnel to potentially dangerous voltages.n
1. Inductive Voltage Transformers (IVT): IVTs use an air-gapped transformer with one winding primary and two windings secondary (centertapped). They are suitable for high power applications, but their accuracy can be affected by frequency changes. Applications include power systems monitoring, protective relays, and electrical testing.
2. Capacitive Voltage Transformers (CVT): CVTs use a capacitor instead of a transformer to isolate the primary and secondary circuits. They are suitable for low power applications, have high accuracy, and are less sensitive to frequency changes. Applications include precision measurements, instrumentation, and electrical testing.
