Atmospheric Impulse And Swicthing Surge Generator
The HVEX Impulse Generator represents the state of the art in high-voltage testing, custom-designed to precisely meet the requirements for dielectric withstand tests against lightning impulse and switching impulse surges. Its advanced technology allows for the validation of various electrical equipment performance under high-energy transients, ensuring safety and reliability for electrical power systems. Featuring a powerful data acquisition system, the HVEX impulse generator is equipped with 12-bit and 16-bit digitizers, operating at 2.5 Giga samples per second (2.5 GSa/s). This ensures extremely high temporal resolution and accuracy in capturing impulse waveforms. Its optically-isolated control system guarantees operational safety and immunity to interference during testing. Operation is managed through intuitive, Windows-compatible software, enabling easy configuration of test parameters, result storage, and automatic calculation of the oscillation coefficient, fully meeting international normative requirements.
