Winding Resistance Tester

DC resistance tester is a necessary item in factory test of semi-finished products and finished products,overhaul, after changing the tap switch , acceptance test , and prophylactic test of power sector.

It can check the welding quality of the winding joints and whether there is a short circuit between turns in the winding, whether the contact at all positions of the voltage tap switch is in good condition , weather the actual position of the tap switch match the indicated position, weather the lead line is broken,whether there are broken shares,etc .This instrument adopts new power supply technology, in small volume, light weight , large output current,good repeatability, strong anti-interference, perfect protection function ,etc.

The whole device is controlled by high speed single chip microcomputer with high degree of automation,with automatic discharge and discharge alarm function. It has many advantages, such asw high precision and easy operation, which can realize the rapid measurement of direct resistance of transformer.
