Abstract

A simulated-noise signal 3 is injected on the power line of the equipment under test without loss of AC power to the equipment, by a series resonance 4, 5 circuit having a resonance frequency equal to that of the AC power supply. The circuit is connected in the power line L1, L2 in series with the equipment 2, and a capacitor 6 is connected to the power line in parallel with the series resonance circuit and the equipment. Therefore, the simulated-noise signal 3 is injected on the power line through the capacitor at both ends of the resonance circuit, and AC power loss is prevented by use of the resonance circuit. A switching element 7 is used to short-circuit the resonance circuit for a period when the noise simulation is not carried out. Simulation of lightning strikes and ringing-surge due to turn-on or -off of other equipment is described.
