TOFT Transformer Load and No-load Characteristic Testing Equipment

Measure the transformer load current, load loss, short-circuit voltage, short circuit (load) losses.  

1. Measure the transformer no-load current, no-load loss, short-circuit voltage, short circuit (load) loss 

2.  Harmonic test can be analyzed to 31 harmonics. 

3. Support two test methods of three-meter method and two-meter method.

4. When carrying out three-phase transformer no-load and load test, the instrument can automatically judge if the wiring is correct
and shows three-phase voltage and current vector diagram.

5.  The single machine can do full current load test for distribution transformer below 1000KVA ; in one third of the rated current,
it can complete up to 2500KVA distribution transformer load test (in one third of the rated current, it can be converted to load
loss parameters under rated current. The machine is mainly used with transformer synthetic test-bed to achieve high-precision
transformer no-load and load test).

6.  All the test results are automatically corrected such as waveform correction, temperature correction, non-rated voltage
correction, non-rated current correction etc. To get more accurate test results.

7.320x240 large screen and high brightness LCD display; full English menu and operation prompts to achieve friendly man-machine
interaction; touch buttons make operation more convenient; wide temperature LCD with brightness adjustment adapted to different
seasons.

8. 40 groups of sample parameters can be preset by the user. These parameters can be deleted or added according to need, very
convenient.

9.  Comes with real-time electronic clock; automatically records test date and time, good for storage and management of results.
10. Panel-type thermal printer quickly print test results on site.

11.  Data (sample set, test results, test time, etc.) with power-down storage and browsing functions. It can store 500 groups of test
results and be connected with computer to transfer date.

12.  Allows external voltage transformer and current transformer for extended range measurement; can test samples of any parameter.
