Protection function: differential quick break protection;Proportional differential protection with second harmonic restraint;CT disconnection locking proportional differential protection;CT disconnection alarm;Auxiliary function fault recording;Measurement and control functions IA, IB, IC; Ia, Ib, Ic; electrical quantities of DIa, DIB, DIC.Communication mode 485 communication;Ethernet;Optical fiber communication;Differential protection principle: the range of differential protection is the range of current transformers on both sides or three sides;The faults outside the protection range do not act, so it is not necessary to cooperate with the protection of adjacent components on the setting value, which can form a timeless quick break protection, which is used to protect the phase to phase fault, turn to turn fault of transformer windings and the ground fault of transformer windings and outgoing lines in the large grounding current system
