Voltage impulse tester 7700

high-voltagecomparisoncoil

Features ■ High voltage calibration ■ programmable impulse voltage ■ Built-in storage 200 sets testing waveform ■ Total area comparison ■ Differential area comparison ■ Wave comparison ■ Flat and Corona ■ Support RS-232, remote and printer interfaces ■ Key lock function to prevent operators from accidentally touching the keys MICROTEST 7700 Impulse Winding Tester offers pulse voltage outputs ranging from 200V to 5000V. It utilizes damping attenuation waveforms generated by L/C resonance to analyze magnetic components for defects such as short circuits between coils or between layers of winding wire. The tester provides various comparison modes, including total area comparison, area difference comparison, corona count comparison, jitter count comparison, and waveform comparison. These modes help identify and detect faulty products accurately.
