Full compensating system of electric current based on phase to earth fault

The utility model provides a full compensating system of electric current based on phase to earth fault, this system include controlling means, trouble phase transfer device, arc extinction coil arrangement and paid compensation arrangement. When the ground connection type that takes place phase to earth fault is instantaneity ground connection, through the arc extinction coil arrangement compensation ground connection capacitance current who has highly sensitive nature to the discernment of high resistant ground connection. When the ground connection type that takes place phase to earth faultis non - instantaneity ground connection, will be closed with the trouble phase transfer earthing device that the trouble is connected mutually, realize that fault current truns into earth current to, and then export the trouble residual flow of full compensation through paid compensation arrangement. It can also regard as paid compensation arrangement to trail the signal of compensation earth current to trun into fault
