WebVoltage Transformers (VT) –inductive or capacitive –are used for voltage metering and protection in high voltage network systems. They transform the high voltage into low … WebThe high frequency carrier signal is coupled to the overhead transmission line via high voltage coupling capacitors of value around 5,000 pF. These act as a low impedance (few hundred ohms) at carrier frequencies but as an open circuit at power frequency (~0.6 MΩ at 50 Hz), thus isolating the radio equipment from the power equipment.
