Aiming at disadvantages of existing GIS partial discharge detection equipment

an alarming system based on GSM and WSNs for GIS partial discharge is designed. GIS partial discharge alarming system consists of an information transfer station and some sensor nodes. Sensor nodes obtain GIS ’ working status information and send the information to the information transfer station by nRF24l01 wireless module

then the information transfer station sends information to GIS station manager through GSM module

which realize efficient and real-time online monitoring on GIS partial discharge. Test results show that the system is simple

economical

stable and extensive in monitoring range

when GIS partial discharge occurs

the system can accurately send alarm information; sensor node is powered by 1000 m Ah lithium battery

which can continue to work for more than 211 d and information transfer station is powered by 20 Ah lead-acid battery

which can continue to work for more than 58 days.
