I. Product Overview

Dc resistance of transformer is a necessary item of semi-finished products in transformer manufacturing, factory test of finished products, installation, handover test and preventive test of electric power department. It can effectively find the material selection, welding, loosening of connection part, missing, broken line and other manufacturing defects and hidden dangers after operation of transformer coil.
