Impulse Voltage Generator

More Information


The SGDA impulse generators are the perfect solution for carrying out impulse tests on HV or UHV cables (5 kJ version) as well as on MV and HV power transformers (10 kJ version). Their small footprint and stable design meet the needs of universities and R&D centers. And with its unique Δ-structure, the SGDA impulse generators are easy to transport and erect onsite.The SGDA series are available for 5 or 10 kJ stage energy, with total charging voltages from 400 kV up to 3000 kV. Also, this system features the lowest internal inductance ever achieved and is well-suited for transformer manufacturers.
