AC three-phase three wire transmission and distribution system, in which the way of ungrounded or high impedance grounding has the advantages unparalleled in other ways. In this system, single phase grounding, although it does not damage the system symmetry operation, but due to the non fault phase voltage V 3 times, if not timely treatment, easy development of two-phase earth short circuit. In order to eliminate the single-phase grounding fault quickly, the key is to have the correct detection of the protection device of the single-phase grounding fault loop.
The JDZ (GRB) series grounding signal device has the characteristics of reliable action, high sensitivity, simple wiring and cheap price. It is composed of an earthing current converter (JDL1) and a ground protector (JDX1). The device takes into account the pressure limiting measures through large current, and can withstand the capacity of short circuit current flowing through the different phase two points.
