The zero-sequence current transformer is used in conjunction with the relay protection device or signal when the power system generates zero-sequence grounding current to make the device components act and realize protection or monitoring.
When an electric shock or leakage fault occurs in the circuit, the secondary side of the transformer outputs the zero-sequence current, so that the equipment on the connected secondary line can be protected (cut off the power supply, alarm, etc.).
- Widely applied to relaying protection field;
- Adoption of ABS flame-retardant plastic shell;
- Epoxy resin casting encapsulation, strong insulation and isolation capability, moisture proof and seismic resistance;
