The temperature of power cable junction is an important parameter to reflect its operating condition.Through measuring and monitoring the temperature of the junction

the aging of insulation can be obtained

its operating condition can be correctly evaluated and the hidden malfunctions can be found in time.A flexible and convenient detection system of power cable joint temperature for underground grid is designed adopting detection technique

computer technique and communication technique etc.And the structure and the advantage of this system are introduced.It is of great significance for preventing cable fire

enhancing the safety and reliability of cable and increasing the economic benefits of the enterprise.
