Product Description

GDHG-108A CT/PT Tester supports test voltage method to test bushings CTs which installed on transformer or inside switch-gear, suitable for the laboratory and on-site detection.

It can be easily and conveniently done voltage current characteristic, transformer ratio, ratio and phase angle error, load test items on CT/PT.

Features

Using the voltage detection principle to measure CT and PT.
To meet the requirements of GB1207, GB1208, GB168-47 (IEC60044-1.6) and other standards.
No external auxiliary equipment, a single machine can complete all test items.
With high speed micro printer: real-time print the test result.
Using intelligent controller, operation is simple.
5inch LCD screen display.
Automatically given CT/PT (excitation) knee point value.
Auto display 5% and 10% error curve.
Save 3000 groups data, it won’t lost after power off.
With USB port. The data can be saved in USB disk and read by PC (WORD format file).
Light weight, less than 22 kg, suitable for onsite testing.
