Product Description

HV HIPOT GDZT-3A Portable Transformer Short Circuit Impedance Tester



Low-voltage short-circuit impedance measurement is basic subject in routine test. Comparing the short-circuit impedance value of transformers before and after short-current impact, to estimate winding distortion degree according to variable value. The changes of transformer impedance should not be over 2%.
LV short circuit impedance test is the most direct way to check winding distortion when the transformers are impacted by short circuit current or mechanic shocked by transportation and installation. It is useful to judge if the transformers can be put into operation.

Features
 

1. With adjustable power output. No matter single phase or 3-phase transformers, the instrument could finish test for all windings by only one time cable connection.
2. For 3-phase transformers, short-circuit impedance, inductance and reactance of each phase can be obtained automatically after boosting each phase.
3. Using internal phase-locked loop technology, synchronous sampling AC signals, measurement data is accurate.
4. Voltage, current, power, frequency can be measured.
5. Wide current range. Support external CT, PT to expand the measurement range.
6. Data will be stored for long time even power off. Built-in printer to print results.
7. Testing data can be imported into PC for analysis or storage.
8. Menu with operation tips, simple and intuitive.
9. LCD screen, clear to see even in direct sunlight.
