Introduction:
GDZC Series Transformer Winding Resistance Tester is used for testing, installing and exchanging the semi-finished or finished transformer.
GDZC Series Transformer Winding Resistance Tester is also a necessity for power department to do preventive trials.
GDZC Series Transformer Winding Resistance Tester 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.
In order to meet the need of fast measurement of DC resistance, our company makes use of our technological advantage to develop the Micro Ohmmeter;
Features:
1) Transformer coil DC resistance measurement
2) Current transformer coil DC resistance measurement
3) Voltage transformer coil DC resistance measurement
4) Generator stator coil DC resistance measurement
5) Discharge the detected coil after the measurement is completed
6) The instrument comes with a thermal printer to print measurement data.
7) The randomly configured PC application software can upload the stored test data and export the test data in WORD format to make a WORD format report.
8) GDZC Series Transformer Winding Resistance Tester is suitable for large-scale transformer above240MVA in temperature rising tests.
9) 840MVA transformer low-voltage direct-resistance tester completed within 2 minutes and the data is stable and accurate.
10) Dual-channel shows the measurement data at the same time.
11) Each interval of 60 seconds automatically print data.
12) Equipped with temperature conversion software, curve waveforms.
Characteristics:
a) Small size, light weight, and extremely low output current ripple factor.
b) The test current gear has a wide selection range and can cover the DC resistance test of various types of transformers.
c) With the test process disconnection protection function, even if the clip is dropped during the test, the tester will not be lost.
d) High test accuracy and good repeatability.
e) Built-in automatic discharge circuit, the discharge of the transformer coil is automatically completed after the test is completed.
f) There are many current gear positions and a wide range.
