Transmission Line Parameters Live Measuring Technology

With working frequency voltage and current, mutual inductance voltage up to 30kV and mutual inductance current up to 50A, measuring instruments can not offset mutual inductance voltage and mutual inductance current interference. The current test mutual inductance parameter must be the same poles of two lines powering outage at the same time. To solve this technical problem, development of transmission lines mutual inductance parameter live testing device, using the device can be achieved under the condition with the tower and rack (or parallel) lines of other circuits running live tests mutual inductance parameters. And expounds the hazards of mutual inductance parameters in the grid and discusses the theoretical basis of the live test equipment and major components.
