Impulse Voltage Generators


Impulse voltage testing systems are designed to generate impulse voltages that simulate lightning strikes and switching surges. Impulse generators are a perfect solution for carrying out impulse tests on HV or UHV cables as well as on MV and HV power transformers. The complete test system consists of a charging rectifier, impulse stages according to the “Marx Circuit”, an impulse voltage divider and impulse voltage measurement system. The applications are defined by IEC, ANSI/IEEE and other national standards.

Impulse Test Sets are also available as Current Impulse Generators used primarily for surge arrestor testing.

HV TECHNOLOGIES, Inc. has a long tradition of supplying impulse generators for HV applications as well as impulse test systems for the EMC, avionics, and military industries.
