Product Details
1. Product Name
Winding Resistance Meter HYZC-40
2. General Introduction
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. Which 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 windings
and large power output inductor equipment.
