Product Description

Features

1. Measure transformer No-load current, No-load loss, short circuit voltage, short circuit loss and capacity.
2. Automatic range switching, voltage measurement and broad current range.
3. When making three phase transformer No-load, load test, the instrument will judge if the wiring is correct automatically, and shows three phase voltage, current vector diagram.
4. Finish load test of 1000kVA or below distribution transformer under full current for single machine. Finish 3150kVA or below distribution transformer load test under 1/3 rated current (Under 1/3 rated current, the load loss parameters of rated current can be converted.)
5. All test results are corrected automatically. The automatic correction includes waveform correction, temperature correction, Non rated voltage correction and non rated current correction.The test results are more accurate.
6. 320*240 high brightness LCD screen, with brightness adjustment.
7. Real-time clock, recording test date automatically, suitable for storage and management of test results.
8. Built-in thermal printer, fast print test results.
9. Power down storage and browse data (test object setting, measurement results, test time) functions. Store up to 500groups test results, data can be transmitted to PC.
10. Allow extended range measurement of connecting with external voltage transformer and current transformer. Measure test object with any parameters.
