For directly detecting temperature of the contacts and bus of high voltage switch
this paper presents a detection method by making use of fiber-optic technology.An AVR microcontroller is adopted to control light source
the optical signal with temperature information is coupled into LOG114 chip for photo-electric conversion through modulation via light intensity type optical fiber temperature sensor
and A/D conversion of the output signal is then performed by the AVR microcontroller to obtain high-precision temperature values through calculation.The system has the features of high precision
