Customer FAQ
What is the difference between an impulse generator and an impulse test system?
An impulse generator is the core component that generates the high-voltage impulse. A complete impulse test system normally includes the generator plus charging equipment, waveform control, voltage measurement, control software and safety systems.
Can one system test different products?
Yes, provided the system is designed with the required voltage, energy, waveform and test circuit flexibility.
Can the system test cables?
Yes. Cable impulse testing is one possible application, although the required configuration depends strongly on cable capacitance and test voltage.
Can it test GIS?
Yes. The system can be engineered for GIS impulse testing, with the test circuit designed according to the GIS specifications and applicable standards.
Is automatic operation available?
Yes. Automatic charging, triggering, measurement and data recording can be integrated into the complete system.
Is customization available?
Yes. High-voltage impulse test equipment is typically customized according to test voltage, energy, waveform, load capacitance, laboratory dimensions and testing standards.
What is the biggest factor when selecting the system?
The most important parameters are usually test voltage, stored energy, test object capacitance, required waveform, measurement accuracy and applicable testing standard.
