Voltage Selection Cabinet SHON for Generating High Voltage Signals (35-750 kV)

SHON voltage sampling cabinet is designed to generate signals equivalent to phase voltage of transmission lines of power lines of 35-750 kV classes with earthed neutral for synchronisation, measurement, protection devices of power lines. The main functions of SHON: <ul> <li>- passing of industrial frequency current from the CS and formation of normalised currents and voltages at specified loads.</li> <li>Providing connection of feeder filters (FF) to the same coupling capacitor (CC) with minimum distortion of FF characteristics.</li> </ul>The electrical scheme of the SHON provides for the presence of 2 voltage selection transformers (VST): one - to supply synchronisation devices; the second - to supply synchronism and voltage control relays.
