Current Transformer Secondary Overvoltage Protector
First, overview
Current transformer (CT) is widely used in primary measurement, control and protection in power systems.When normal work, the secondary side in approximate short circuit state, output voltage is very low, but in operation if the secondary winding open circuit, or a winding through abnormal current (such as lightning current, resonance current, capacitor charging current, inductor start current, etc.), will be in the secondary side of thousands or even tens of thousands of volts of overvoltage, this not only to the secondary system insulation harm, and even endanger the safety of the staff.
The CTB secondary overvoltage protector of CT B series current transformer produced by our company is designed for this situation, which can effectively prevent accidents caused by C T secondary open circuit.
