Transformer power analyzer

Type: ZC-201A
ZC- 201A transformer power analyzer can measure no-load current, no-load loss, short-circuit voltage and short-circuit (load) loss of transformer. It can carry out harmonic test and analyze to the 31st harmonic. The instrument automatically switches the measuring range inside, allowing a wide range of measuring voltage, current and simple wiring. During the no-load and load test of three-phase transformer, the instrument can automatically judge whether the wiring is correct and display the vector diagram of three-phase voltage and current.

Product Features
1. It can measure no-load current, no-load loss, short-circuit voltage and short-circuit (load) loss of transformer.
2. Transformer harmonic test can be carried out.
3. The instrument automatically switches the measuring range inside, allowing a wide range of measuring voltage, current and simple wiring.
4. During the no-load and load test of three-phase transformer, the instrument can automatically judge whether the wiring is correct and display the vector diagram of three-phase voltage and current.
5. Single machine can complete the measurement of load test under the full current of distribution transformer below 100kVA; under the third rated current, it can complete the measurement of load test of distribution transformer below 250kVA (under the third rated current, the instrument can be converted to the load loss parameter under the rated current).
6. All test results are automatically corrected. The instrument can automatically carry out a variety of corrections, such as: waveform correction, temperature correction, non-rated voltage correction, non-rated current correction, etc., so that the accuracy of the test results is higher.
7. 320x240 large screen, high brightness liquid crystal display, all Chinese menu and operation prompt realize friendly man-machine dialogue, touch the key to make the operation easier, wide temperature liquid crystal band brightness adjustment, can adapt to winter and summer seasons.
8. The instrument can preset 40 groups of test object parameters by users, and these parameters can be deleted and added at any time according to needs, which is very convenient to use.
9. It has a real-time electronic clock, which can automatically record the date and time of the test, which is conducive to the storage and management of the test results.
10. Panel thermal printer. The test results can be printed quickly on site.
