◆ The peak value of the voltage is directly measured, effectively avoiding the influence of waveform distortion of the test voltage on the authenticity of the test results

Directly collecting breakdown current from the high voltage side avoids the large errors caused by traditional overload protection methods that sample from the low voltage side

Advanced microcontroller controlled inverter power technology ensures more reliable performance. At the same time, it has a small volume and light weight.

The protection response is fast and the breakdown current is small. Due to the use of advanced microcontroller controlled inverter power technology, the breakdown protection time of this instrument can be easily achieved to be less than 1mS. At the same time, the breakdown current index is less than 5mA, fully meeting the requirements of the new national standard.

The output voltage and current waveform of the inverter power supply are good. The output adopts closed-loop feedback control, ensuring that the voltage and current input on the low-voltage side of the high-voltage transformer are both good positive spiral waves. However, similar instruments simply use a voltage regulator to boost the voltage, and the input power is taken from the mains, almost without any processing before being added to the secondary high-voltage transformer. Although the voltage waveform is still good, the current waveform has varying degrees of distortion, especially when the system power supply is severely contaminated by harmonics or even low-frequency interference, the voltage and current waveforms will have varying degrees of distortion, and the current waveform may even be severely distorted, thereby affecting the accuracy of the test results.

The boost speed can be adjusted within a wide range, with a selection range of 0.5-5KV/S. The boosting process is smooth. Compared to the current advanced method of using stepper motors to control voltage regulators for boosting, microcontroller controlled inverter power technology can make the voltage rise more delicate, continuous, and smooth, adding a basis for the authenticity and reliability of test data.

The software has powerful functions and can clearly indicate the instrument status and related information in Chinese. It automatically completes the entire testing process and can automatically process necessary data through manual selection after the test is completed. The results can also be calculated, and the data that needs to be printed can be printed into a test report using a micro printer.
