    How to Maintain Hipot Tester?

    Different types and uses of hipot testers may be different, but generally, the following maintenance tips can be used for safe pressure measurement. Through regular maintenance and care, the performance of the hipot tester can be ensured to be stable and its service life can be extended. It also helps to reduce downtime caused by equipment failure and improve work efficiency.

    What is a Hipot Tester Used for?

    The hipot tester is an important electrical testing equipment and is widely used in electrical safety testing in various fields. Hipot testers play an important role in electrical safety testing in electronic products, power equipment, the automobile industry, the new energy field, rail transportation, and other fields. By using a hipot tester, potential insulation defects can be effectively discovered, potential electric shock risks can be prevented, and equipment and personal safety can be ensured. The following are specific applications of hipot testers in several major fields.

    How to Calibrate the Hipot Tester?

    A hipot tester is an instrument used to test the withstand voltage capabilities of electrical devices, insulating materials, and insulating structures. The hipot tester usually consists of three modules: a program-controlled power supply module, a signal acquisition and conditioning module, and a computer control system. The hipot tester is an important tool for checking the voltage withstand capability of insulating materials and insulating structures, so its calibration and maintenance are crucial to ensure the accuracy and reliability of test results.

    How to Test a Hipot Tester?

    Exports are rising, and China has established itself as a major industrial hub for electrical and technological goods. Along with consumer product safety, manufacturers are always enhancing product safety requirements in accordance with pertinent international laws and regulations. Additionally, before a product leaves the plant, it is thoroughly inspected for safety by the maker. The product's electrical function's safety, or perhaps its resistance to electric shock, is also a crucial component of the inspection.

    The product's planning, construction, and insulation materials all have matching requirements or specifications that may be understood in order to comprehend how well the product insulates. Manufacturers typically employ a variety of inspection and testing techniques. However, a test is required for electrical products, and the electrical strength test can reveal whether the product performs well overall in terms of insulation.

    Many different withstand voltage testers are available on the market right now. Manufacturers must increasingly prioritize cost-cutting in order to purchase practical withstand voltage testers for investments and internal purposes.

    Safe Operation of Hipot Tester

    The principle of hipot tester is to apply a voltage higher than normal working voltage to the insulator of the device under test for a specified period of time. If the insulation is good enough, the voltage applied to it will only produce a small leakage current. If a device maintains its leakage current within the specified range for a specified period of time, it can be determined that the device under test can operate safely under normal operating conditions. This article will introduce safe operation of hipot tester.

    What is a Hipot Tester?

    Hipot tester, also called dielectric strength tester, is used to carry out the test of applying a specified AC or DC high voltage between the live part and the non-live part of the electric appliance to check the hipot of the insulating material of the electric appliance. In long-term work, electrical appliances must not only bear the effect of rated working voltage, but also bear the effect of overvoltage that is higher than the rated working voltage for a short time during operation(The overvoltage value may be several times higher than the rated working voltage value). Under the action of these voltages, the internal structure of electrical insulating materials will change. When the overvoltage intensity reaches a certain value, it will cause the insulation breakdown of the material. The electrical appliances will not operate normally, and the operator may get an electric shock, endangering personal safety. The main electrical safety test indicators include AC/DC hipot, insulation resistance, leakage current, ground resistance, etc. AC/DC hipot tester is used to test the electrical safety performance of the product under actual working conditions, so it is one of the important instruments for testing the electrical safety performance of the equipment.

    The DC hi-pot tester, though with a higher test voltage, is found with insulation weaknesses, but the insulation of electric appliances is mostly composite dielectrics, whose voltage is distributed by resistance under the effect of DC voltage. Therefore, the DC hi-pot test might not find out the weaknesses of the DC electric appliances under the AC electric field. On the contrary, the AC hi pot tester is in line with the electric conditions imposed on the electric appliance during its operation process. Meanwhile, the AC hi-pot tester is generally higher than the operating voltage. Therefore, after passing the test, the appliance can gain a larger safety margin, so this test has been a major method to guarantee operation safety.
