Impulse Voltage Generator, Brand Name : Grandtop

Application
giv series impulse voltage test systems can be used to generate impulse voltages simulating lightning impulse (1.2±30%50±20%μs), chopped lightning impulse, switching impulse (250±10%2500±10% μs) and steep front waveforms.
With special design, they can be used to test large capacitance electrical apparatus, such as gis and cables.
With small inductance, they can be applicable for testing the large capacity transformers.
The generator carries out specific tests for industry and research applications.
