ABB REF541KM118AAAA motor protection device It uses digital signal processing technology, can quickly and accurately detect feeder faults, achieve rapid fault removal, and ensure the stable operation of the power system. Intelligent feeder terminal structure: Intelligent feeder terminal is generally composed of a control part, a data processing part, a communication part and a power supply part. Control part: energy storage of circuit breaker, closing operation, opening operation. Data processing: Integrated FTU, relying on FTU to complete data collection and processing. Communication part: Integrated communication module, 4G wireless communication, optical fiber communication, etc. Power supply: built-in battery or supercapacitor, power supply including AC/DC220,DC48.DC24, etc. The previous secondary node is the new primary node and takes over the progressive execution of the program.

The function of feeder protection measurement and control device is an important protection device in the power system. Its main function is to remove the fault quickly and protect the stable operation of the power system when the feeder is short circuit, ground fault or other abnormal conditions. 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 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.
