Check whether the “Voltage Adjustment” knob of the hipot tester is fully turned counterclockwise. If not, rotate it all the way. Plug in the power cord of the hipot tester and turn on the power switch of the instrument. Select the appropriate voltage range: Set the voltage range switch to the “5kV” position. Select the …
AC DC hipot tester is also called electrical insulation strength tester or dielectric strength tester. A test of applying a specified AC DC high voltage between the live part and the non-live part (usually the casing) of the electrical appliance to check the withstand voltage capability of the insulating material of the electrical appliance. AC …
Voltage calibration 1. The hipot tester is in reset mode, and the voltage adjustment knob is turned counterclockwise to the end. 2. Connect the high voltage meter to the hipot tester. 3. Press the start button, adjust the voltage output button, so that the reading of the high voltage meter is the value of the …

The operator must wear insulating rubber gloves and put insulating rubber pads under the feet to prevent life-threatening high-voltage electric shocks. 1. The hipot tester must be grounded reliably. 2. When connecting the detachable DUT, it must be ensured that the high voltage output is “0” and in the “reset” state. 3. During the test, …
Avoid exposure to rain and humidity The oil cup and electrode should be kept clean and protected with new transformer oil during the out-of-service period. The insulating oil hipot tester often checks whether the distance between the electrodes has changed, and whether the screw thread between the electrode head and the electrode rod is loose. If …
The cable hipot tester is a general-purpose high-voltage test instrument, which is widely used in the hipot test of electrical equipment, bakelite appliances, transformer power cords, electric energy meters, motors, power plugs and sockets, cables, etc. pressure test. With the establishment of safety standards in various countries, the cable hipot tester has become an indispensable …
First, high pressure tests are affected by humidity and temperature. Humidity: When the high-voltage test section is carried out, it must be carried out under shielding conditions, and the test process will be affected by the air humidity, which will affect the accuracy of the experimental data. For the measured data, it is impossible to …
Purpose In order to correctly carry out the functional self-test of the hipot tester, ensure the correctness and validity of the test results. Steps 1. Ground the hipot tester case before use to ensure good and reliable grounding. 2. Plug in the plug, input power to the hipot tester, and place the high-voltage output line …

Hipot tester is a test that applies a specified AC or DC high voltage between the live part and the non-live part (usually the casing) of the electrical appliance to check the withstand voltage capability of the insulating material of the electrical appliance. In the long-term operation of electrical appliances, not only the rated working …
Be sure to read the manual carefully before use, and follow the instructions to operate. The hipot tester and the object to be tested must be well grounded, and are not allowed to be tied to the tap water pipe at will. The high voltage generated by the hipot tester is enough to cause casualties. …
