Product Introduction
The DC resistance of transformers is a necessary test item for semi-finished and finished products in transformer manufacturing, factory testing, installation, handover testing, and preventive testing by the power department. It can effectively detect manufacturing defects such as material selection, welding, loose connection parts, missing strands, and broken wires of transformer coils, as well as hidden dangers after operation.
The ED0204-10B DC resistance tester is an innovative product with a built-in large capacity lithium battery. The instrument and testing line are designed as a single unit, and the product is compact in size and easy to carry. The product is not only suitable for measuring inductive samples such as transformers, transformers, and reactors, but also for measuring resistive samples such as copper bars, wires, and switch contacts. The instrument testing speed is fast and the accuracy is high.
