Abstract :
Researched on a kind of photoelectric current transformer based on the Rogowski coil, it solved the electrical insulating problem between the high and low voltage sides using the optical fiber to transmit the pulse signal from the high-pressure side. The laser energy can meet the demand of electricity in high voltage side steadily. The V/F conversion of digital signal processing method makes the transmission signal has a strong anti-interference ability, and experimental results show that the maximum error is 0.2% in the range of 0~50A.
