Wiressless temperature monitoring solution was majorly designed for monitoring and alarming the temperature of crucial electrical connection nodes in switchgear like busbar, power cable, cable&busbar connection, CB's fixed contact, CB's moving contact and etc. Such electrical connection nodes have the potential threat of fire hazard due to the aging of material, slackness of connection and etc. Thus a real-time temperature monitoring and alarm system will be necessary to prevent it from potential fire hazard caused by the risingof temperature.
