ED0204-10B DC Resistance Tester

Product Overview

The transformer's DC resistance is a mandatory test item during the production process, including semi-finished and finished product factory tests, installation, handover tests, and preventive tests by the power department. It effectively identifies manufacturing defects such as material selection, welding, loose connections, missing strands, and broken wires in the transformer's windings, as well as potential hazards that may arise after operation.

The ED0204-10B DC Resistance Tester is an innovative product featuring an integrated large-capacity lithium battery. It combines the instrument with the testing cable in a single design, making the product compact and easy to carry. The product is suitable not only for measuring inductive test pieces such as transformers, mutual inductors, and reactors but also for resistive test pieces like copper bars, wires, and switch contacts. The instrument offers fast testing speed and high accuracy.
