Product Description

Transformer No-load/load  Loss Test Device 


I. Feature 

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

1. Allows an external voltage transformer and current transformer for extended range of measurement, any measurable parameter is the test product.
2. Data (test sample set, the measurement results, the test of time, etc.) with power-down storage and browsing features, you can store 500 set of experimental results with computer on-line data transfer.
3. Panel-type thermal printer, the scene quickly print test results.
4. Comes with real-time clock, automatically recording test date, time, the preservation of favorable results, management.
5. The instrument 40 can be preset by the user group is the test product parameters, and these parameters can be removed according to need and increase in use is very convenient.
6. 320x240 large screen, high brightness LCD display, full Chinese menu and operations to achieve prompt and friendly man-machine dialogue, touch buttons make the operation more convenient, wide LCD with brightness adjustment, can be adapted to the various summer and winter season.
7. All the related test results are automatically corrected. Instrument can automatically such as: the waveform correction, temperature correction, non-rated voltage correction, calibration, and other non-rated current correction, so that more accurate test results.
8. Single machine can do the following 100KVA distribution transformer full load current experiment; in one third of the rated current, complete 250KVA distribution transformer load the following test (in one third of the rated current, the instrument can be converted to load loss under rated current parameters, the machine is mainly used in the test bed with integrated supporting the use of transformers, the load characteristics to achieve high-precision transformer no-load test).
9. Do three-phase transformer no-load, load test, the instrument can automatically determine the wiring is correct, and shows three-phase voltage and current vector map.
10. Support Three Watt Meter, two table method, two experimental methods.
11. Harmonic test can be analyzed to 31 harmonics.
