Relay Type Switch Circuit Test in High-Voltage Impulse Generator - This kind of impulse generator simulates transient overvoltages on residential or industrial low-voltages AC power circuits (120 or 220V).

And the following picture diagrams basic schematic circuit of the tester for high-voltage impulse generator in the relay type switch with resonant circuit.

And herein are the value description of basic impulse generator circuit semiconductors :
