RIG500 Recurrent Impulse Generator

The RIG500 is a compact and versatile recurrent impulse generator engineered for impulse voltage testing, fault localization, and simulation in electrical machines, transformers, and components. With precise control over impulse shape, peak voltage, and chopping parameters, the RIG500 is ideal for R&D laboratories, universities, and diagnostic applications in the power sector.

It provides flexible waveform configuration, adjustable circuit parameters, and built-in chopping control, making it an invaluable platform for insulation studies, transient analysis, and education.
