Fiber-optic-based current and Voltage measuring system for high-Voltage distribution lines

  title={Fiber-optic-based current and Voltage measuring system for high-Voltage distribution lines},
  author={M. M. Werneck and A.C.S. Abrantes},
  journal={IEEE Transactions on Power Delivery},
A system for temporary measurement of voltage and current simultaneously in high-voltage distribution lines was developed. The sensing heads use a resistive divider and a magnetic pickup for sampling voltage and current, respectively. A self-powered transmitter converts both signals into a pulse-frequency-modulated optical signal for transmission in multimode optical fiber. At ground potential, the optical signal is received and demodulated back into voltage and current signals. Then, a… CONTINUE READING
