Project Description
Product Features:
The DC resistance tester adopts a brand-new power supply technology and has the characteristics of small size, light weight, and large output current. The whole machine is controlled by a single-chip microcomputer, with a high degree of automation, with automatic discharge and discharge indication functions.
The instrument has a large output current and is light in weight.
It has a complete protection circuit and strong reliability.
The vertical chassis structure is convenient for on-site operation.
It has a discharge alarm sound and a clear discharge indicator to reduce misoperation.
The instrument has high test accuracy and easy operation, which can realize rapid measurement of transformer direct resistance.
Transformer DC resistance is a must-test item in transformer manufacturing for semi-finished products, finished products factory test, installation, handover test and preventive test of the power department. It can effectively find manufacturing defects such as material selection, welding, loose connection parts, lack of strands, and disconnection of transformer coils. And hidden dangers after operation. In order to meet the needs of rapid measurement of transformer DC resistance, the LTZR-40A DC resistance tester developed by our company.
