Product Introduction
this product is specially used for measuring the capacity of distribution power transformer measuring the no-load and short-circuit loss of transformer and has the function of harmonic analysis which is convenient for analyzing the quality of on-site power network. the device can automatically check whether the wiring is correct and display the vector diagram of the three-phase current and voltage when testing the three-phase transformer. At the same time necessary correction (such as waveform correction temperature correction unrated voltage correction calibration unrated current correction) is introduced to make the test results more accurate.

Product Characteristics
1. Measure the transformer no-load current no-load loss; short-circuit voltage short circuit (load) loss capacity.
2. Test methods: three-table.
3. the device can auto check if the wire was correctly connected and display the vector diagram of three phase current voltage when test the three phase transformer.
4. Single machine can make the loading test for substation transformer under 1600KVA; can make the loading test with 1/3 of the rated current for substation transformer under 2500KVA (the device can convert to the loading losses parameters if the rated current under 1/3 of the rated current)
5. 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.
6. 320x240 LCD friendly man-machine interface brilliance control adapts to all seasons.
7. with electronic clock auto record the data time it is good for saving and managing the test results.
8. Panel type printer can print the test results on site.
9. Data (specimen setting test results measurement time) can be saved on power failure and can be reviewed it can store 500 groups test results can connect with computers to transmit data.
10. Allow external connecting CT and PT to make extension measurement can test the specimen with any parameters.
