Product Description

Product Overview

 

The transformer energy efficiency grade comprehensive tester is a precision instrument used to measure transformer capacity, no-load, load and other characteristic parameters. This instrument is a multi-functional measuring instrument, equivalent to the usual two test instruments: transformer capacity tester + transformer no-load tester. It can accurately measure a series of power frequency parameters such as capacity, type, no-load current, no-load loss, short-circuit (load) loss, impedance voltage, etc. of various transformers. This product has many advantages such as small size, light weight, high measurement accuracy, good stability, and simple operation. It can replace the previous method of using multiple meters to measure transformer loss and capacity. The wiring is simpler, and testing and recording are more convenient, which greatly improves your work efficiency.

Functional characteristics

1. It can accurately measure the capacity of various distribution transformers, conveniently and accurately.

2. It can measure the transformer's no-load loss, no-load current, load loss, impedance voltage, voltage RMS, voltage average value, current, power, power factor, frequency and other parameters.

3. The instrument automatically switches the range, allowing a wide range of voltage and current to be measured, and the wiring is simple.

4. When doing no-load and load tests on three-phase transformers, the instrument can automatically determine whether the wiring is correct and display the vector diagram of the three-phase voltage and current.

5. It has the function of using a single-phase test power supply to measure impedance in phase

6. It has the function of directly and automatically measuring within the measurement range allowed by the instrument, and can connect a primary voltage transformer and current transformer when the measurement range is exceeded

7. It has the function of automatic waveform distortion correction, voltage correction, current correction, and temperature correction

8. It has the function of manually setting the test current and test frequency when measuring impedance voltage

9. It has the function of manually setting the test current and test frequency when measuring no-load current

10. A single machine can complete the measurement of load tests under full current for distribution transformers below 1000KVA; it can complete the measurement of load tests for distribution transformers below 3150KVA at one-third of the rated current (at one-third of the rated current, the instrument can convert to the load loss parameters at the rated current).

11. Combined with external power supply and voltage regulation, voltage boosting, current boosting and other equipment, it can measure the no-load current, no-load loss, impedance voltage, short-circuit (load) loss and other transformer characteristic data of various transformers. It can measure the no-load current, no-load loss, impedance voltage and load loss of various types of transformers.

12. In the transformer characteristic measurement, the maximum voltage range can reach 750V, the maximum current range can reach 100A, and it is equipped with a protection circuit inside. When measuring, there is no need to switch gears to ensure measurement accuracy, and there is no need to worry about burning the instrument due to wrong gear selection

13. It can automatically perform waveform distortion correction, temperature correction, voltage correction (no-load test under non-rated voltage), and current correction (load test under non-rated current conditions). The operator only needs to input the correction index according to the transformer type, and the instrument can automatically calculate the corrected results. It is suitable for units that do not have the conditions for short-circuit test of slightly larger capacity transformers.

14. According to the no-load and load losses in the test results, the performance level of three-phase oil-immersed distribution transformers and power transformers can be automatically estimated for on-site reference by staff. Users can print out the test data through a micro printer at any time.

15. All test results are automatically corrected. The instrument can automatically perform multiple corrections such as waveform correction, temperature correction, non-rated voltage correction, non-rated current correction, etc., to make the test results more accurate.

16. The 320x240 large screen, high-brightness LCD display, Chinese character menu and operation prompts realize friendly human-computer dialogue, touch buttons make operation easier, and the wide-temperature LCD has brightness adjustment, which can adapt to winter and summer seasons.

17. The instrument can preset 40 groups of test product parameters by the user, and these parameters can be deleted and added at any time as needed, which is very convenient to use.

18. It has a real-time electronic clock that automatically records the date and time of the test, which is conducive to the preservation and management of the test results.

19. The panel thermal printer can quickly print the test results on site.

20. The data (test product settings, measurement results, test time, etc.) has power-off storage and browsing functions, can store 500 groups of test results, and can transmit data online with a computer.

21. It allows external voltage transformers and current transformers to perform extended range measurements, and can measure test products of any parameters.
