Product Description
Ultrasonic Flaw Detector from HV Hipot is a non-destructive testing device used for detecting internal mechanical damages for electrical equipments.


It detects internal flaws of electrical equipments, such as bushings, busbars, wire clamps, transformer tank, current & voltage transformers, surge arresters, generator bearing equipment, and porcelain pillar type insulators, etc.


TFT true color screen.
High accuracy and wide applications.
High sensitivity of flaw detection, up to 110dB.
Built-in stantard curves and test block for pilliar type insulators. The device alarms if internal crackle flaws are superstandard.
Automatic calibrations for probe and curvature surface, which optimizes the coupling between the probe and test object and ensures accuracy.
Aluminum alloy chassis from Germany, which has excellent anti-jamming performance. Low noise and high signal-to-noise ratio.
