Recloser is a kind of intelligent switch equipment used in distribution network automation. Four-Faith F-FTU200 series can detect fault current, disconnect the fault current within a set time, and perform a given number of recloses. A control switch with "own" capability. 

Four-faith overhead fault indicator positioning system is composed of external application signal source, acquisition unit, collection unit and main station system.

Environment condition of outdoor ring net ark is different, complex. High temperature is prone to fire, low temperature will form condensation and short circuit and other accidents, temperature and humidity exceeding a certain threshold will affect the normal operation of distribution function, it is very important to monitor and adjust the environmental state of ring network cabinet.

The Four-Faith communication management machine F-DPU100 supports multiple protocol conversions, adopts high-performance industrial-grade wireless modules and 32-bit communication processors, and is equipped with a WTD watchdog design to ensure system stability and permanent online equipment. 

In the power industry, the Internet of Things technology has been widely used, especially wireless communication technologies such as LoRa, NB-IoT, 3G / 4G, etc. are particularly important in the field of power meter reading, which is also an inevitable trend of the development of the IoT electrification.
