摘要：
By the two-fiber way to power for the probe in high voltage side and convey the pulse signal, the Rogowski coil photoelectric current transformer is constructed, solving the problem of electrical insulation between high and low voltage sides. The photoelectric conversion efficiency of optical fiber power supply may reach 50%, which can meet the demand of electricity utilization steadily. The digital signal processing method of V/F conversion makes the signal transmission has a strong anti-interference ability, and the experimental results show that this method for maximum error is 2 parts per thousand in the input range of 0 similar to 50A.
