HZ-3110 10A Transformer DC Resistance Test Set

The HZ-3110 DC Resistance Tester features advanced technology, compact size, light weight, and high output current capability.

Controlled by a microcontroller, the device offers a high degree of automation and includes an automatic discharge function. It is a high-precision test instrument that provides a simple and direct method for rapid transformer measurement.

DC resistance testing is an essential procedure for transformer semi-finished and finished product testing, installation, commissioning, and preventive maintenance of electrical components. This test effectively identifies issues such as poor welding, loose connections, missing strands, open circuits, manufacturing defects, and other hidden faults that may occur after operation.
