Abstract
A kind of 10KV power distribution network fault indicator integrating measurement and communication functions was researched and developed. Used in 10KV power distribution overhead lines, this indicator is also designed with the communication module, current and temperature measurement module in addition to having the function of plate turning indication in case of grounding or short circuit fault. Through a wireless communication mode, the fault or measurement information is sent to the nearby data terminal unit, which sends the data to the monitoring center through the GPRS network. Workers will know the working status of the whole power distribution network in a real-time manner through the computer of the monitoring center. By adopting the ATmega8L MCU as the core, the new type of fault indicator realizes the wireless data transmission function through NRF24L01.
