Overview

GAOTek  hand-held DC Ground Fault locator the tester is a portable device, small in size and light in weight. Has the characteristics of simple operation, high precision, anti-interference, shockproof, convenient to carry, etc. Adopts large-capacity lithium battery, which can be used continuously for more than 6 hours on a single charge to meet the requirements of field test. Has perfect inverse potential protection function; Measurement speed is fast, measurement data is accurate and stable; Testing process is controlled by a microcomputer, which automatically completes self-calibration, stable flow judgment, data processing and resistance value display. The longitudinal test of DC resistance of on-load voltage regulator transformer can be completed by a single power supply. It is suitable for rapid measurement of dc resistance of transformers with voltage grades up to 110kV. Transparent large LCD screen that displays clearly in sunlight.
