Transformer comprehensive tester is a multifunctional on-site testing instrument designed specifically for testing the volt ampere characteristics, transformation ratio, polarity, error curve, calculation inflection point, AC withstand voltage, and secondary side circuit inspection of transformers.

1. MBC power control technology, single-phase AC220V input power supply, and the working power supply shares the same input port with the power supply, making the design more scientific and reasonable, and the use safer and more reliable.
2. The power output of the device is the true voltage and current values, and the waveform is a standard sine wave with a frequency of 50-60Hz; Can truly and effectively simulate the true state of the transformer, in compliance with relevant national maintenance regulations.
3. The maximum voltage output of a single machine with 220V input is 0-1000V, and the maximum current output of a single machine is 0-600A.
4. It can detect the volt ampere characteristics, transformation ratio, polarity, 5% and 10% error curves, CT primary current and CT demagnetization of CT/PT, and easily achieve multi-purpose use of one machine.
5. Adopting a single power input port; CT/PT testing can be completed with only 8 test ports, and the wiring method is safe and simple, making it very suitable for on-site use. It can effectively reduce labor intensity and improve work efficiency;
6. For CT variable ratio measurement ranges of 25000A/5A and 5000A/1A. PT ratio test range 500KV: 100V
7. Using a thermal printer to automatically screen and print typical report usage data, it is very suitable for on-site data comparison.
8. Can save 1000 sets of experimental data without losing it after power failure.
9. Easy to connect to modern laptops.
10. Small size and light weight: convenient for on-site use.
