When the transformer is cross-connected, overhauled or some of its switches are changed, direct current resistance testing of the transformer winding is necessary;
In general, to measure the transformer winding or large power output indicator 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, we 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.
This Micro Ohmmeter is an idealequipment for measuring transformer winding and large power output inductor equipment.
It is used for testing, installing and exchanging the semi-finished or finished transformer.
This Micro Ohmmeter can effectively help you to find disfigurements in the manufacturing of transformer, such as the winding choosing, welding, loose joints, missing shares and hidden danger in the running.
It is suitable for large-scale transformer above240MVA in temperature rising tests.
840MVA transformer low-voltage direct-resistance tester completed within 2 minutes and the data is stable and accurate.
Dual-channel shows the measurement data at the same time.
Each interval of 60 seconds automatically print data.
This Micro Ohmmeter is equipped with temperature conversion software, curve waveforms.
