Overview
The insulation equipment of lightning impulse high-voltage generators is mainly used for conducting impulse voltage tests on power equipment and other test samples, including full wave lightning impulse voltage, lightning impulse voltage cutoff, and operational impulse voltage waves, to test the insulation performance. A surge voltage generator is a power supply device that simulates surge voltages such as lightning and operating overvoltage. Mainly used in insulation impulse withstand voltage and dielectric impulse breakdown, discharge and other tests.
