<p>PURPOSE:To accomplish a load interruption test handily, by making a voltage waveform obtained during the interruption of a resonance current at the zero- point equivalent to that obtained during the testing with an AC test circuit. CONSTITUTION:A first reactor 7, a second reactor 8 and a load switch 3 are connected sequentially in series to a capacitor 6 as power source to form a resonance circuit. Then, a first resistance 9 and a first capacitor 10 are connected in series between the reactors 7 and 8 while a second resistance 11 and a second capacitor 12 are connected in series to a side end of a switch 3 of the reactor 8. With such an arrangement, a voltage waveform obtained during the interruption of a resonance current at the zero-point can be almost equivalent to that obtained during the testing with an AC test circuit thereby making a load interruption test of the switch 3 very handy.</p> |
