The DC Winding Resistance Tester is an essential instrument for transformer testing, including semi-finished product testing, finished product testing, installation commissioning, and electrical preventive maintenance testing. This handheld device effectively identifies manufacturing defects and operational hazards such as poor welding, loose connections, missing units, wire breaks, and other potential issues in transformer coils.
Designed to meet rapid measurement requirements, our DC Winding Resistance Tester incorporates powerful new technology with compact size, lightweight design, and high output current capabilities. Controlled by a single-chip microcomputer, the instrument features high automation levels, automatic discharge functions, and delivers high-precision testing with straightforward operation for fast transformer measurements.
