Jiangsu Huafang Electric specializes in the production of frequency series resonance withstand voltage test device for thirty years, has accumulated a lot of frequency series resonance withstand voltage test device is easy to appear in the actual use of the "difficult problem", to help users solve the problem. On February 26, 2017, a user in Tangshan called Huafang to ask the frequency series resonance withstand voltage test device will appear in the actual use of the phenomenon of voltage drop what is the reason, how to solve?

Website editor and the user for a detailed inquiry, understanding, he described the situation is this: to a cable voltage withstand test, when the instrument according to the set voltage boost and time to start, suddenly the voltage is unstable, the voltage value quickly decline until zero, thus leading to the test failure.
After communicating with the company's technical department and actually simulating the experiment, we concluded that the voltage drop after boosting the frequency series resonance withstand voltage test device is not a failure of the instrument, and analyzed the following main reason: the test piece discharge or breakdown.

Therefore, Jiangsu Huafang Electric suggests that the user in the use of frequency series resonance withstand voltage test device to the cable test, be sure to be a detailed inspection of the test article, test insulation resistance meets the requirements of the test after the withstand voltage test, in order to ensure the safety of the person, the equipment and the test process is an effective success!
A friendly reminder: it is recommended to establish a separate power supply line for the frequency series resonance withstand voltage test device.
