AC High Voltage Testing Set is designed for testing various electrical equipment and consists of a double wound HV transformer with the high tension end is brought at the top for testing up to the rating of 300 kV. The Set has the feature that the last end of the high tension winding is also brought down, through intermediate circuitry and is ended on the earth connection. The Set has the feature that if the current in the under test equipment increases above the prescribed value, the intermediate circuitry allows for the tripping the supply to the high tension transformer. The AC High Voltage Testing Set comes equipped with the provision of a zero start interlock switch and variance which allows the slow application of high voltage to the test specimen.
