With the development of power industry, the safety and reliability of equipment are highly demanding. In the past, the method of manual inspection equipment has been gradually weakened, under this condition, the wireless temperature measurement system of high voltage equipment came into being. This technology is to install the temperature sensor with built-in battery and wireless transmitting module at each temperature measuring point. Because of its small size and no connection, its electrical safety can be guaranteed. The sensor periodically sends the temperature measurement data wirelessly to the receiver, and it can send the data to the main station on a network, so as to realize the electrical temperature monitoring of a regional system.

Currently, many power grid companies, substations and steel companies in China have adopted this wireless temperature monitoring technology on high voltage equipment.

The electric terminal on-line temperature measuring device is using for the temperature monitoring of cable connector, circuit breaker contact, knife switch, high voltage cable intermediate head, dry transformer, low voltage high current and other equipment in high and low voltage switch gear.To prevent excessive contact resistance caused by oxidation, loosening, dust and other factors during operation, heating becomes a hidden danger of safety, to improve the safety and security of equipment, to reflect the running state of equipment in time, continuously and accurately, and to reduce the accident rate of equipment.
