The main advantages and characteristics of a comprehensive tester for transformers

The transformer comprehensive tester, also known as the transformer volt ampere characteristic tester, is an essential tool for power workers to test the wiring method, working principle, and ferromagnetic resonance characteristics of transformers.

The CTA-1000C variable frequency transformer comprehensive tester is a new generation of innovative CT and PT testing instruments developed on the basis of traditional transformer voltage ampere characteristic ratio polarity comprehensive testers based on regulators, boosters, and current boosters. It extensively listens to user opinions, conducts extensive market research, and conducts in-depth theoretical research. The device adopts high-performance DSP and FPGA, advanced manufacturing technology, ensuring stable and reliable product performance, complete functions, high automation level, high testing efficiency, and leading level in China. It is a professional testing instrument used for transformers in the power industry.

The CTP-1000C variable frequency volt ampere characteristic tester meets the following requirements:

1. Suitable for conducting transformer calibration in electric power research institutes;

2. Suitable for factory calibration by transformer manufacturers;

3. Meet the preventive testing requirements of the power sector;

4. Meet the handover test requirements for engineering units and cabinet enterprises.

The following are its main advantages and characteristics:

1. It has comprehensive functions and can meet the testing requirements of excitation characteristics (i.e. volt ampere characteristics), transformer ratio, polarity, secondary winding resistance, secondary load, ratio difference, and angle difference of various CTs (such as protection, metering, TP). It can also be used for testing excitation characteristics, transformer ratio, polarity, secondary winding resistance, ratio difference, and other tests of various PT electromagnetic units.

2. On site calibration of current transformers does not require standard current transformers, current transformers, load boxes, voltage regulation control boxes, and high current conductors. It uses extremely simple testing wiring and operation to achieve current transformer calibration, greatly reducing work intensity and improving work efficiency, making it easy to carry out on-site transformer calibration work.

3. It can accurately measure the CT ratio difference and angle difference, with a ratio difference * allowable error of ± 0.05% and an angle difference * allowable error of ± 2 minutes. It can measure 0.2S level current transformers, with a ratio measurement range of 1-40000.

4. Based on advanced frequency conversion method to test CT/PT volt ampere characteristic curve and 10% error curve, the output is only 180V AC voltage and 12Arms (36A peak) AC current, but it can withstand CT testing with a turning point of up to 60KV.

5. Automatically provide CT and PT parameters such as inflection point voltage/current, 10% (5%) error curve, accuracy limit factor (ALF), instrument safety factor (FS), secondary time constant (Ts), residual magnetization coefficient (Kr), saturated and unsaturated inductance.

6. Test to meet various transformer standards such as GB1208 (IEC60044-1), GB16847 (IEC60044-6), GB1207, and automatically select which standard to test based on the type and level of the transformer.

7. The testing is simple and convenient, with one click completion of CT direct resistance, excitation, ratio and polarity testing. In addition to load testing, all other CT tests are conducted using the same wiring method.

8. Full English dynamic graphical interface, no need to refer to the manual to complete wiring and parameter settings: dynamic display of parameter settings, automatically displaying relevant parameters based on the currently selected test project; Dynamically display the help wiring diagram, displaying the corresponding wiring diagram based on the currently selected test project.

9. 5.7-inch graphic reflective LCD, clear and visible under sunlight.

10. Using a rotating photoelectric mouse operation, the operation is simple, fast, convenient, and extremely easy to master.

11. The panel comes with a printer that can automatically print generated test reports.

12. The test results can be exported from a USB drive, and the program can be upgraded using a USB drive, which is convenient and fast.

13. The device can store 1000 sets of test data without losing power.

14. Equipped with backend analysis software, it facilitates the storage, conversion, and analysis of test reports, and can be used for comparison, judgment, and evaluation of experimental data.

15. Easy to carry, device weight<9Kg.

In summary, the transformer comprehensive tester not only has high-precision measurement capabilities, but also has a wide testing range and convenient operation characteristics, making it an indispensable testing tool in the power industry.
