Profile:
The active transformer characteristic capacity comprehensive tester is a high-precision instrument developed and researched by our company specifically for measuring transformer capacity and loss parameters to address this issue. It comes with a high-performance rechargeable battery and can work without an external power source. It can measure 100 units continuously after one charge; At the same time, the 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) 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 improving work efficiency; The accuracy of the capacity test results is 100%. It is equivalent to two devices: an active transformer capacity tester and a transformer loss parameter tester. 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. This instrument has the advantages of small size, light weight, high measurement accuracy, good stability, and easy operation and learning. It can replace the previous method of measuring transformer loss and capacity using multiple meters. The wiring is simple, the testing and recording are convenient, and the work efficiency is improved. It uses a large screen LCD as the display window, with graphical menu operations and text prompts. It integrates multiple parameters into a single screen display interface, with a user-friendly human-machine dialogue interface. It is easy and fast to use, and is a product for power users at all levels.
Features:
1. Can accurately measure the capacity of various distribution transformers, passive measurement, convenient and accurate.
2. Internally equipped power supply, automatically generating three-phase high-power test power supply.
3. It can measure the no-load current, no-load loss, short-circuit voltage, and short-circuit loss of various types of transformers.
4. It can automatically perform waveform distortion correction, temperature correction, voltage correction (no-load test under non rated voltage), and current correction (short-circuit test under non rated current conditions). Operators only need to input the correction index instrument according to the transformer type to automatically calculate the corrected results, which is very suitable for units that do not have slightly larger capacity transformer short-circuit test conditions.
5. Voltage circuit width limit: The maximum voltage that can be measured is 750V, and accuracy can be ensured without switching gears. The instrument itself will not be damaged due to incorrect voltage gear selection.
6. The function of indicating the percentage of remaining battery power is not simply a low power alarm.
7. Large screen, high brightness LCD display, user-friendly human-machine dialogue with operation prompts, touch buttons for easier operation, wide temperature LCD with brightness adjustment, suitable for winter and summer seasons.
8. Users can print out the results of the test data at any time through a micro printer.
9. The test result storage function can store 200 sets of capacity test data.
