Overview

Brick technology: By using parallel compensation method and only one reactor, the AC withstand voltage test of the generator can be carried out at the power frequency, simplifying the original generator AC withstand voltage test equipment that weighed hundreds of kilograms or even several tons to only 120 kilograms, greatly reducing the workload on site. The tester cleverly adopts the principle of compensating inductance current for capacitance current in electrical principles. On the basis of ensuring that the power frequency frequency and waveform remain unchanged, the number of test equipment components and the weight of the test instrument are greatly reduced

Generator AC voltage withstand tester

The XT-100 portable generator AC (DC) withstand voltage tester cleverly adopts the compensation principle of inductor current to capacitor current in electrical principles. On the basis of ensuring that the power frequency and waveform remain unchanged, it greatly reduces the number of test equipment components and the weight of the test instrument, reducing the total weight of the test equipment from several hundred kilograms or even a few tons in the past to 120 kilograms now. The portable generator AC (DC) withstand voltage tester has truly achieved the effects of being lightweight, safe, and efficient through on-site testing. Replacing the cumbersome and cumbersome experimental equipment of the past,Greatly reduces the workload on site.Moreover, the instrument is equipped with a DC withstand voltage test function, which allows for the DC withstand voltage test of the generator when on-site conditions permit, providing great convenience for electrical testing personnel and testing work in power plants.

Equipment advantages:

1. Lightweight equipment:

The weight is one twentieth of the original;
The capacity is one tenth of the original;

2. Easy to operate;

3. Do not generate resonance overvoltage and capacitance overvoltage;

4. The required power capacity for the experiment is small:

The original experimental method requires a test power supply of 72kVA,
Now only 7.2kVA is needed

5. The voltage waveform is not distorted;

6. The instrument is compatible with both AC and DC, and has good completeness;

The AC/DC withstand voltage test can be completed with one set of instruments.
