FAQ
Q:What is an impulse voltage generator used for?
It is used to generate controlled high-voltage impulses for evaluating the insulation withstand capability of electrical equipment under transient voltage conditions.
Q:What is the difference between lightning impulse and switching impulse?
Lightning impulse testing simulates fast transient overvoltages associated with lightning, while switching impulse testing represents slower transient stresses caused by switching operations in power systems.
Q:What is the maximum voltage available?
Depending on the configuration, the SXCY Series can reach ±4800 kV.
Q:How many stages can the generator have?
The available configurations shown in the product specifications range from 1 to 24 stages.
Q:What determines the required generator size?
The required impulse voltage, test object capacitance, energy requirement, test waveform and applicable testing standard are key factors when selecting the generator configuration.
