Three-Phase Transformer Winding Resistance Tester , Transformer Ohm Meter
I. Products Description and Application
Transformer DC resistance test is one of the most important test item in the finished product and semi-finished product factory test, installation and hand-over test in the transformer manufacturing and in the preventive test of the electric power sector it can effectively find manufacturing defects such as looseness, strand lack and broken line in the material selection, welding and connection part of the transformer coils and the hidden danger existing after running.
In order to meet the demand for quick measurement of transformer DC resistance. Our company has developed a new generation of DC resistance tester by making use of own technical advantages, . Using the brand new third-generation power supply technology, it has small volume, light weight and large output current, etc.
TWR series Transformer Winding Resistance Tester(TWR) is applied for measuring winding DC resistance of power transformers , it is an ideal instrument for power system , transformer manufacturers and railway electrical systems.
