Automatically cut single-phase earthing fault: when the user tributary line cause a single-phase earthing fault, the boundary switch will open automatically, and other distribution line users of the substation and feeding line will be without influence; isolation interphase short circuit fault automatically.
When the tributary line cause interphase short-circuit fault, the boundary switch will open at once after out-wire protection tripping. After the substation recloses, the fault line is isolated passively, and other distribution users in the feeding line resume power supply rapidly(equal to a transient fault).
Quick localization of fault: the tributary line fault causes boundary switch protection action, only the accident user cause a power cut, and by itself reports the fault information, the power company could dispatch a worker to live investigation; if the boundary switch match with a communication module, it could transmit a message to the electricity management center.
Monitoring user's load, the boundary switch could configure wired or wireless communication enclosure to monitor data and transmit it to the electricity management center, making the achievement of real-time data monitoring of users' load over long distances.
The function of a network running, could be used in network lines, the function of measurement, monitor voltage, current, frequency, and quantity of electricity of lines, and transmit to the management center in long distance. The function of harmonic analyzing is to supply a reliable basis for pollution administration of electricity net afterward.
