The BOHG-105 comprehensive characteristic tester for transformers is a multifunctional on-site testing instrument designed specifically for testing the volt ampere characteristics, transformation ratio, polarity, error curve, angle difference ratio, calculation of inflection point, and secondary side circuit inspection of transformers

During the experiment, only the test voltage/current value needs to be set, and the equipment can automatically boost/boost the current, and quickly display the voltage current characteristic curve or transformation ratio, polarity and other experimental results of the transformer. It supports data saving and on-site printing, which not only saves the tedious labor of manual voltage regulation, manual recording, curve drawing, but also uploads the test data to the computer for editing, saving or printing through the USB interface Easy to operate and improve work efficiency, it is a high-tech product with high cost-effectiveness

1. Safe and reliable

The first MBC power control technology in China, single-phase AC220V input power supply, and the working power supply shares the same input port with the power supply. The design is more scientific and reasonable, and the use is safer and more reliable

Note: Other similar products use separate input methods for working power and power supply, and also require the use of three-phase AC380V dual live input to meet experimental requirements, which poses a great safety hazard and can easily cause accidents such as electric shock and even injury to users

2. Complies with national maintenance regulations

The power output of the device is all 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 transformers, in compliance with relevant national maintenance regulations

3. Large output capacity

The maximum voltage output of a single machine with 220V input is 0-1000V/2500V/3000V/6000V (depending on the model), and the maximum current output of a single machine is 0-600A/1000A (depending on the model), which is very suitable for on-site maintenance and use

4. Fully functional

It can detect the volt ampere characteristics, transformation ratio, polarity, 5% and 10% error curves, angular difference ratio, CT primary current and CT demagnetization of CT/PT, and easily achieve multi-purpose use of one machine

5. Simple wiring method

Adopting a single power input port; With only 8 test ports, all CT/PT testing projects can be completed. 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. Large testing scope

For CT variable ratio measurement ranges of 15000A/5A and 3000A/1A PT ratio test range 500kV: 100V

Note: Measurement range without the need for an external booster or an external current booster

7. Quick printing

Using a thermal printer to automatically screen and print typical report usage data, it is very suitable for on-site data comparison

8. Large capacity FLASH storage

Can save 1000 sets of experimental data, and can be saved for 10 years after power failure

9. USB interface

Convenient to connect to modern laptops

10. Small size, light weight
