China High Quality Test Arrester fault Manufacturer – GDUD-PBI Ultrasonic Flaw Detector for Electrical Equipment – HV Hipot

Applications

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

Features

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