SYSTEM FOR SENSING CURRENT IN HIGH VOLTAGE TRANSMISSION LINES UTILIZING THE TRANSMISSION OF DIGITAL INFORMATION BY OPTICAL FIBERS |
摘要 |
A system and a method for sensing and reproducing a measured current value on a high voltage transmission line. An input shunt means senses a current to be measured. A transmitter circuit transmits a sampled current value of the current passing through the shunt means. The transmitter has converter circuits for reproducing a composite output digital coded signal representative of the sample current value. A light transmitting output means is provided for transmission of the composite output digital coded signal on an optical fiber transmission line to a receiver circuit. The receiver circuit has decoding circuit means for decoding and reconstituting the coded signal to a usable form to determine the sampled current value. |
