The function of feeder protection measurement and control device

Feeder protection measurement and control device is an important protection equipment in the power system, its main function is to quickly remove the fault when the feeder occurs short circuit, ground fault or other abnormal conditions, to protect the stable operation of the power system. It can sense the abnormal current and voltage signal in the power system, and compare it with the preset fault protection conditions. When the fault is detected, it can quickly cut off the fault link and prevent the fault from spreading to the power grid.

Principle of feeder protection measurement and control device

The working principle of the feeder protection measurement and control device is based on the current and voltage sensors installed on the feeder line, through the fault signal detection, measurement, processing, fault judgment and rapid removal. It adopts digital signal processing technology, which can detect feeder fault quickly and accurately, realize fast fault removal, and ensure the stable operation of power system.
