Current Transformer Protection - Open-Circuit Conditions ... Current Transformer (CT) is used to measure the current of another circuit. CTs are used worldwide to monitor high-voltage lines across national power grids. A CT is designed to produce an alternating current in its secondary winding that is proportional to the current that it is measuring in its primary.

Effect of Moisture inside SF6 Gas Insulated Switchgear· When switching is done in a SF6 Gas insulated switchgear, arching will occur. This is because there is a high impedance on the breaker switch when the switch is opened and high voltage current tries to flow through the impedance. The arching release immense heat and SF6 gasses will quench the arching in order to prevent it from spreading.
