Dc high voltage generator has over current, over voltage and zero voltage start and fault protection function, among them, over current and over voltage protection setting function is more perfect, if necessary, can carry out sound and light alarm, so as to ensure that the potentiometer must return to zero before each voltage boost; In addition, the voltage protection value can be set, the set voltage can be visually displayed.

The DC high voltage generator can smoothly adjust the output voltage in the full range, and can also be converted to about 75% of the voltage output at any time, with a voltage conversion of about 0.75 times, which provides convenience for testing the zinc oxide arrester. In addition, the output voltage will not be affected when the discharge bar is used. The output voltage can also be timed, in the case of full load can also work up to about 30min.

There is no dc high voltage generator pressure doubling cylinder boost mode:

How to boost the pressure of the voltage doubling cylinder without DC high voltage generator? The pressure doubling cylinder is built-in, as long as the power cable, cable and ground wire are connected well.

How to boost the current limiting resistance of the voltage doubling cylinder without DC high voltage generator

When doing the cable test, it is necessary to connect one end of the current limiting resistance with the upper end of the pressure doubling cylinder, and then connect the other end of the current limiting resistance with the microammeter. Note: The current limiting resistance is only used for capacitive load tests (including cable tests). It is not required for other tests.
