HZ-3150A 50A Transformer DC Winding Resistance Test Set
DC resistance test set is mainly used for the measurement of DC resistance of large and medium-sized transformers, engines, motors, etc. the instrument is set with multiple current gears to meet Add to Inquiry
The test can be conducted on the complete windings, but the interpretation is easier when the test is performed on individual coils. Shorted Turns in Field Windings. The flux probe test is aimed...
DC resistance test. This test is very straightforward. Using a digital low resistance ohmmeter (DLRO), we apply a 10-amp current through the rotor winding circuit and measure the voltage...
Winding resistance, the resistance of a length of copper wires or bars from one end to the other, is a measure of DC voltage and current and the application of Ohm’s law as follows: where R is...
Apr 01, 2020 · The motor winding resistance test uses the “Four-wire” (Kelvin) measurement method. It provides the best possible measurement results since it ensures that the resistance...
