Transformer no-load short-circuit characteristic tester

Capacity characteristic tester for power transformersProduct Introduction
Transformer no-load short-circuit characteristic testerIt is a precision instrument developed and manufactured by Yangzhou Topu Electric Technology Co., Ltd. specifically for measuring transformer capacity and loss parameters. It comes with a high-performance rechargeable battery and can work without an external power source. It can measure 500 units continuously after one charge; Internal digital synthesis of three-phase standard sine wave signals (not simply inverted AC output, ensuring the accuracy of test data for various test items under non rated conditions), which can provide a three-phase precision AC test source through a power amplifier; When measuring the capacity and short-circuit loss of transformers, there is no need for external three-phase testing power supply, voltage regulator, current boosting and other auxiliary equipment, simplifying wiring and greatly improving work efficiency.
Transformer no-load short-circuit characteristic testerThe accuracy of the capacity test results is high. It is equivalent to four types of equipment: active transformer capacity tester+transformer loss parameter tester+harmonic analyzer+oscilloscope. It can accurately measure a series of power frequency parameters such as capacity, no-load current, no-load loss, short-circuit loss, impedance voltage, etc. of various transformers, and can measure the voltage, current distortion, and harmonic content during no-load testing. It can also perform vector analysis.
This active transformer capacity characteristic tester has the advantages of small size, light weight, high measurement accuracy, good stability, and easy to operate and learn. It can replace the previous method of measuring transformer losses and capacity using multiple meters. The wiring is simple, the testing and recording are convenient, and it greatly improves the performanceImproved work efficiency. It uses a large screen color LCD as the display window, menu operation with Chinese character prompts, and a display interface that integrates multiple parameters on one screen. The human-machine dialogue interface is friendly, easy to use, and fast.

Main functions
1. The instrument comes with an internal power supply that automatically generates a three-phase high-power test power supply.
2. Can accurately measure the capacity of various distribution transformers, passive measurement, convenient and accurate.
3. It can measure the no-load current, no-load loss, short-circuit voltage, and short-circuit loss of various types of transformers.
4. The model of the tested transformer can be accurately determined through no-load testing, including various types of transformers such as S7, S9, S11, S13, S15, dry transformers SCB9, SCB10, SCB11, etc.
5. It can automatically perform waveform distortion correction, temperature correction (providing two methods of simple temperature correction and additional loss correction), voltage correction (no-load test under non rated voltage), and current correction (short-circuit test under non rated current conditions), which is very suitable for those who have not done a slight correctionUnit for short-circuit test conditions of large capacity transformers.
6. It can measure the harmonic content and total harmonic distortion of voltage and current.
7. Can perform simple vector analysis and draw vector diagrams.
8. Display waveform diagrams of various electrical parameters for use as oscilloscopes.
9. Voltage circuit width limit: The maximum voltage can be measured up to 750V without switching gears to ensure accuracy. The instrument itself will not be damaged due to incorrect voltage gear selection.
10. Capacity measurement range: 20kVA to 100000kVA.
11. The function of indicating the percentage of remaining battery power is not simply a low power alarm.
12. Large screen, high brightness color LCD display, full Chinese character menu and operation prompts for friendly human-machine dialogue, conductive silicone touch buttons for easier operation and longer button life.
13. Users can print out the results of the test data at any time through a micro printer.
14. The test result storage function can store 200 sets of capacity test data.
