A Study of the On-line Testing Method and Monitor of Temperature Rise in the Switchgear

摘要

In the paper a device for monitoring the temperature rise in the switchgear is introduced. THe monitor uses the optical fiber technology to effect the isolation and ssolves the problem of the ocntinuous power supply of the transducer. The temperature at any point in the switchgear can be monitored on line without affecting the normal operation of the switchgear.
