20A DC Resistance Tester

Product Overview

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

 ED0204-10BThe Type DC Resistance Tester is an innovative product featuring an internal high-capacity lithium battery. The instrument and test lines are designed as a single unit, making the product compact and easy to carry. The tester is suitable for measuring inductive test pieces such as transformers, current transformers, and reactors, as well as resistive test pieces like copper bars, wires, and switch contact points. It boasts fast testing speed and high accuracy.
