By high capacity high-speed switch, the series reactor is shorted during normal operation, eliminating the reactor leakagemagneticflux to eddy hot produced metal member around it.
A measuring method combining main magneticflux and magneticfluxleakage for approaching the residual wall thickness of the oil well tubing in-service was presented.
