HV Equipment

SGVA (Up to 10,000 kV)


The sophisticated design of the SGVA series considers all requirements of impulse voltage tests imposed by industry and research. This series offers reliable and accurate triggering on account of its patented parallel spark gap leading to low impulse circuit inductance. Resistors are distributed within the generator, stored in easily-accessible compartments, accessible through platforms and internal ladders for rapid stage access and interchangeability. An integrated base frame carries both the generator and the charging rectifier.
