【Abstract】 A digitalized optical fiber current measurement technology is introduced. Rogowski coil is used to sense the detected current, A/D to realize digitalization of signal and optical fiber to transmit the digital light signal. Microprocessor fulfills signal communication and processing. The measurement results and waveform are shown on the screens of LCD and computer. Tests show that the linearity of the system is within 0.2%,and the current waveform can be displayed correctly.更多还原
