The transformer comprehensive tester is a multi-functional on-site testing instrument specially designed for testing the伏安 characteristics, transformation ratio, polarity, error curve, calculating the inflection point, and checking the secondary circuit of transformers. During the experiment, only the test voltage/current values need to be set, and the equipment can automatically increase the voltage/current and quickly display the伏安 characteristics curve or the transformation ratio, polarity, and other experimental results of the transformer. It supports data saving and on-site printing. Not only does it eliminate the cumbersome manual voltage adjustment, manual recording, and curve drawing, but it can also upload the test data to a computer for editing, saving, or printing via the USB interface.
1. Safe and reliable：
The first-of-its-kind MBC power control technology is adopted, with a single-phase AC 220V input power supply, and the working power supply and power supply share the same input port. The design is more scientific and reasonable, and the use is safer and more reliable.
2. Compliant with national maintenance regulations：
The equipment’s power output is all real voltage and current values, and the waveform is a standard sine wave, with a frequency of 50-60Hz. It can truly effectively simulate the real state of the transformer, meeting the relevant maintenance regulations of the country.
3. Large output capacity：
When using a single 220V input, the larger voltage output of the unit is 0-1000V, and the larger current output is 0-600A. It is very suitable for on-site maintenance use.
4. Complete functions：
It can detect the伏安 characteristics, transformation ratio, polarity, 5% and 10% error curves, CT primary current flow and CT demagnetization of CT/PT, and easily achieve multi-purpose use with one machine.
5. Simple wiring method：
It adopts a single power input port; with only 8 test ports, all test items of CT/PT can be completed, the wiring method is safe and simple, and it is very suitable for on-site use, effectively reducing labor intensity and improving work efficiency；
6. Wide testing range：
For CT transformation ratio measurement range of 15，000A/5A and 3000A/1A， and PT transformation ratio testing range of 500KV： 100V. Note： The measurement range without the need for an external booster or external current booster.
7. Quick printing：
It uses a thermal printer， automatically screening and printing typical reports using data， which is very suitable for on-site data comparison.
8. Large-capacity FLASH storage： It can save 1000 sets of test data， and the data will not be lost even after power loss.
9. USB interface： Supports U disk storage function， convenient for data transfer.
10. Small size， light weight： Convenient for on-site use.
11. Built-in perpetual calendar， automatically saves the detection date.
