Abstract：Considering to the joint temperature medium voltage power cable terminal accessory is too high and the aging problem of insulation， an online monitoring system is designed for medium voltage cable terminal fault， and gives the hardware circuit structure principle of the system and each module design. The lower computer takes MSP430F149 as the core， sets the temperature sensor， the fault current sensor， the high voltage electricity sensor in an integrated detection unit， which is composed of a cable terminal intelligent detection unit.Each cable terminal monitoring unit of the data using GSM wireless transmission mode to a summary of the LABVIEW platform based on the development of the wireless terminal of the host computer realtime display and storage. By building the hardware circuit， the temperature of the joint， the fault of the circuit and the remote online monitoring of the charged state information are realized， which proves the rationality of the syste...
