Knowing the precautions of the hipot tester will help us strive to use it.
This article describes the norms and measures to be followed when using Hipot tsters using the instrument. When using this instrument, special care must be taken to ensure safety. Warning: This hipot tester has a test high voltage output of 10KVA. If you operate the instrument incorrectly or wrongly, it will cause accidents or even …
A hipot (short for high potential) test determines the ability of electrical insulation to withstand normally occurring over-voltage transients. The hipot tester applies high voltage to the insulation barrier of the DUT and verifies there is no breakdown. It is a simple pass/fail test performed as a type test on a representative sample unit or …
Only properly trained operators should be allowed use the equipment and access the test area. Do not make any connections to a DUT unless you have verifed that the high voltage warning light is OFF. Never touch a DUT, the hipot tester or the test leads. When connecting leads to the DUT, always connect the …
As an important branch of instrumentation, Hipot tester has a wide range of applications, covering industry, agriculture, transportation, science and technology, environmental protection, national defense, aerospace and daily life. Usually, industrial process gas monitoring and analysis instruments are classified into the field of analytical instruments. Common withstand voltage testers are usually miniaturized, portable or fixed, …
Apply a higher than normal voltage to the insulator of the device under test and continue for a period of time. If the insulation is good enough, the applied voltage will only generate a small leakage current; if the leakage current of the insulator of the device under test is within the specified time Stay …
Wiring diagram of hipot tester How to use the hipot tester? Plug in the 220V, 50Hz power supply, connect the high-voltage output line and the output low-end line to the high and low output ends of the instrument respectively, and place the two output line ends in the air; Set the breakdown current according to …
Common faults of DC Hipot test: When the power switch of hipot tester is turned on, the digital indicator on the control box does not light up. Please check the power connection and all the fuses. If the fuse is damaged, please replace it with a new one according to the amperage marked beside the …
We mainly consider the insulation resistance tester in the low-voltage test, and whether it will break down in the high-voltage test. The resistance is extremely low during the breakdown, and it almost becomes a conductor. The insulation resistance test is a qualitative test that gives an indication of the relative quality of an insulation system. …

We all know that the hipot tester is used to detect whether the voltage of the equipment is safe to use. Because its operating object is electricity, it must be more careful when operating it to avoid causing some damage. Manufacturers specializing in the production of hipot testers will tell every customer what to pay …
Test of running Connect one end of the 0.7MΩ standard resistor to the ground wire of the hipot tester. Turn on the power, then set the alarm leakage current of the instrument to 5mA. Turn on the instrument, hit the other end of the standard resistance with a test rod, adjust the voltage from 3410V …
