Impulse Voltage Generators are designed to generate impulse voltages that simulate lightning strikes and switching surges. 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 for testing transformers and power cables.
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 generator for HV applications as well as impulse test systems for the EMC and avionics, military industries.
