DC resistance of transformer is a must-test item of semi-finished product, finished product factory test, installation, handover test and preventive test of power department in transformer manufacturing, which can effectively find manufacturing defects such as material selection, welding, loose connection parts, missing strands, broken wires and other hidden dangers after operation.
The transformer DC resistance tester is an innovative product with a built-in large-capacity lithium battery, which is small in size and easy to carry. The product is not only suitable for the measurement of inductive test products such as transformers, transformers, reactors, but also suitable for the measurement of resistive test products such as copper bars, wires, switch contacts, etc. The instrument test speed is fast and the accuracy is high.
product names： DC resistance tester, transformer DC resistance tester, transformer winding DC resistance tester, transformer direct resistance tester, transformer direct resistance fast tester, inductive load DC resistance tester, inductive load DC resistance fast tester, inductive load DC resistance tester, direct resistance tester
