The working principle is that a voltage higher than normal operation is added to the insulator of the device under test for a specified period of time, and the voltage added to the above will only produce a small leakage current, so the insulation is better. The test system consists of three modules: program-controlled power module, signal acquisition and conditioning module and computer control system, with alarm and time control functions.

1, the device for the touch screen operation control.
2, if you need to perform curve analysis, you can be equipped with a computer, only data and curve recording function, no equipment control, to avoid the test personnel in the computer and equipment alternating operation, more humane.
3, the equipment has the function of memory of test parameters, the same test conditions do not need to be set each test, and the power will still remember the last test set parameters.
4, the test interface is simple and clear, and is equipped with schematic curve description, different parameters, different curve trends, easy to understand.
5, the control panel is simple, the function is clearly marked, the operation is simple.
6, can record and display 10 test records at the same time, convenient for comparative analysis of test data. And can discard the unsatisfactory data in real time.
7, the equipment test interface adopts the real-time display mode, which is more convenient to watch the test process.
8, the equipment has a safety warning, the test can not start when the test chamber door is not closed, and a warning will pop up, and the warning will pop up at the full degree (that is: no output of the high voltage transformer), and if the test is opened during the test, the test will automatically end.
9. The equipment is equipped with three-color alarm. (optional)
