HZ-3120 Transformer DC resistance tester 

Brief introduction

The dc resistance is the essential test item of transformer production of semi-finished products, finished product test, installation, handover testing and power department of preventive test , can effectively found winding materials, welding, joint, lack of shares, break loose and other manufacturing defects and after the operation of the hidden danger.

Features

1. Output current is big, test range wide, small volume, light weight, simple operation

2. Test speed fast, high-accuracy, good reiteration test, Strong anti-interference ability

3. With perfect protection circuit, strong reliability.

4. With the functions of discharge acoustics, discharge the instructions clear, reduce errors operation
