要約(英語): The prospective transient recovery voltage (TRV) at current interruption for circuit breakers should be measured by using an ideal circuit breaker. But it is very difficult to measure the prospective TRV because there is no ideal circuit breaker. Instead of this method, it is often used diodes in low voltage measurements. In this case, it is difficult to decide the current zero by the forward voltage drop of the diode. Furthermore, the maximum value of the TRV becomes small by the forward voltage drop of the diode. Reverse current injection principle is well known to measure the TRV. The prospective TRV for the short circuit testing circuit will be measured by using this reverse current injection principle. But, there was not the reverse current injection circuit until now. In this paper, reverse current injection circuit is constructed. The prospective TRV for breaker terminal fault was measured by the reverse current injection circuit.
