Product Usage
The impulse current generator is mainly used to generate high amplitude lightning impulse current, to test the ability of electrical components and surge protection devices to withstand strong impulse currents. It is also possible to conduct impulse current withstand tests on the valve plates and electrical devices of the oxidation arrester, as well as other electrical equipment, under operating conditions. Widely used in power equipment manufacturing plants, power operation departments, research institutions, and higher education institutions. The product is used to simulate various types of lightning currents, such as 1/<20us, 4/10 us, 8/20us, 18/40 us, 10/350us, 10/1000us, and 2ms square wave impulse current waveforms.
