The Impulse Voltage Generator is designed to assess the insulation strength and surge withstand capability of high-voltage electrical equipment when exposed to transient overvoltage conditions. It provides controlled impulse stresses that simulate lightning strikes and switching events, making it an important solution for product development, quality verification, type testing, and high-voltage research.
Widely used by electrical equipment manufacturers, power utilities, testing laboratories, universities, and research institutions, the system enables reliable impulse testing across a broad range of high-voltage products.

Impulse energy represents the energy available from the generator during an impulse discharge. For the same rated voltage, a generator with insufficient energy may not provide the required test performance for certain large or highly capacitive test objects. Therefore, rated voltage and impulse energy should be considered together when selecting an impulse voltage generator.
Yes. The SXCY Series can be configured for transformer lightning impulse and switching impulse testing, depending on the transformer's voltage class and applicable test requirements. Impulse testing can be used to evaluate transformer insulation against transient overvoltages and verify the dielectric strength of the winding insulation system. For transformer applications, the generator configuration should be selected according to the transformer's rated voltage, insulation level, test voltage, capacitance, and applicable standard.
