A method to measure the temperature of the bus bar for switchgear cubicle on-line monitoring system is presented in this paper. With a sensor being contacted with the measured point, the signal of temperature at high potential is modulated into optical pulse. The receiver at earth potential an cubicle receives the optical pulse and restores the signal of temperature. It's a good and accurate method with short response time and high accuracy.
