JK3810 Active transformer capacity characteristic tester

The JK3810 active transformer capacity characteristic tester is used to test the capacity level of transformers that have lost their nameplates or have doubts about their nameplate markings. It can effectively and accurately test the capacity level of distribution transformers.
Main functions and features:
1. 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. Built in high-performance lithium-ion rechargeable battery with large capacity, capable of testing over 500 units continuously when fully charged.
4. It can measure the no-load current, no-load loss, short-circuit voltage, and short-circuit loss of various types of transformers.
5. 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.
6. Voltage circuit width limit: The voltage can be measured up to 750V, and accuracy can be ensured without switching gears.
7. Capacity measurement range: 20KVA to 100000KVA.
8. Large screen, high brightness LCD display, full Chinese character menu and operation prompts achieve friendly human-machine dialogue.
9. It has the function of storing test data and printing test results.
