Current transformer (hereinafter referred to as CT) in the power system, CT is the high current requirements into a small current, widely used in a measurement, protection and control. It is the meter, meter, and current control system essential kit. CT normal working hours, similar to short-circuit in the transformer secondary side of the state, the output voltage is very low. In operation, if the secondary winding open circuit, or an abnormal current flows through the windings (thundering current, resonance over-current, capacitive charging current, the inductor current starts, etc.), will generate thousands of volts in the secondary or even thousands of volts over the voltage. This is not only harmful to the secondary insulation, but also to make the radical and the transformer burned, and even endanger the lives of the staff.
CTB protection is mainly used for a variety of CT secondary side of the abnormal over-voltage protection. Protection installed in the secondary winding according to both ends of a very small leakage current during normal operation, into a high impedance state. When an abnormal over-voltage, fast action and short circuit protection, fault location on the front panel display, and a passive signal output. When troubleshooting, the circuit returns to normal. Protectors used in a variety of CT secondary side of the differential winding, over-current winding, measuring winding, busbar protection winding, winding back and so on.

In the power system, ferromagnetic resonance frequency occurs, will produce resonance over-voltage, a serious threat to system security. Ferroresonance over-voltage 220 ​​kV in 3 to occur in any system, especially in the 35 kV and below the grid, almost all of the internal over-voltage caused the accident by the ferromagnetic resonance. Ferroresonance over-voltage caused by long duration, even possible long-term existence. In the resonance frequency, the general over-voltage is not high, but the PT's current, easy to overheat and explode the PT; fundamental and harmonic resonance, the general current of small, but over-voltage is high, often makes equipment insulation damage , resulting in accidents.
