Introduction
Features
Parameters
When the transformer is cross-connected, overhauled or some of its switches are changed, direct current resistance testing of the transformer winding is a must. In general, to measure the transformer winding or large power output inductor equipment, the traditional electrical bridge method and pressure drop method require much time and energy. Thus, to shorten the measurement time and reducing the workload of testers, our company developed rapid direct current resistance tester. This is designed with new power supply technology and stable performance, fast measurement, compact, easy to use, high accuracy, good data reproducibility. It is an ideal piece of equipment for measuring transformer winding and large power output inductive equipment.
