Abstract

PURPOSE:To make it possible totest the cutoff performance securely by constituting a current source by a low speed operation shorting generator from which a low frequency current is obtained and a transformer, and constituting a voltage source by a series circuit of a resistor and a capacitor. CONSTITUTION:A switch 18 is closed D, and a low frequency, asummetric, shorting current is conducted to anauxiliary commutation breaker 23 and a commutation breaker to be tested 24. Then the breakers 23 and 24 are opened E at the same time. Then an oscillation current is overlapped on the low frequency current by the mutual action of an auxiliary commutation reactor 21 and an auxiliary commutation capacitor 22. The current IC of the breaker 24 becomes the oscillating current, a zero current point F is generated, and the breakers 23 and 24 are cut off. If a charging voltge for a voltage source capacitor 9 is applied across the breaker 24 by a switch 8 before the cutoff, a voltage VC which is determined by a capacity CO and a resistance r of a resistor 7 is applied. In this constitution, even through the breaker is of a multi-point type, the cutoff is always achieved at the same time, the voltage waveform applied to the breaker 24 becomes constant, and the reliable equivalent test can be performed.
