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 …
Advantages of AC hipot tester 1. The measurement accuracy of leakage current is high. 2. Both positive and negative half weeks can be tested. 3. The equivalent capacitance of the object to be tested has no time to charge and discharge. 4. It can detect all voltage polarities, which is closer to the actual practical situation. …
The hipot tester is also called an electrical dielectric strength tester or a dielectric strength tester. A test of applying 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 …
Hipot tester, also known as electrical insulation strength tester, or dielectric strength tester, also known as dielectric breakdown device, dielectric strength tester, high voltage tester, high voltage breakdown device, hipot tester etc. A test of applying a specified AC or DC high voltage between the live part and the non-live part (usually the casing) of …
The test system has three modules: program-controlled power module, signal acquisition and conditioning module and computer control system. It is composed of a program-controlled power supply with an output position of 0V~140V and a high-voltage transformer. Under the control of the microcontroller ADCm842, the output voltage of the program-controlled power supply can be boosted by …
The hipot tester is a computer control system composed of a high-performance microcontroller ADCm842 as the core. ADCm842 integrates 12-bit A/D and D/A converters and has a DMA controller to complete high-speed conversion from A/D to RAM. The ADCm842 has a superior 8052 core with a peak efficiency of 20 mega instructions per second. ADCm842 …
Composition Principle When the transformer is first produced, hipot tester has not been tested in harsh environments for a long time. The power supply with hipot tester rated voltage and frequency is applied for testing. The voltage between winding turns, layers, and sections are not enough to reach the breakdown voltage of the dielectric defect. …
Hipot tester is also called electrical insulation strength tester or dielectric strength tester, also called dielectric breakdown device, dielectric strength tester, high voltage tester, high voltage breakdown device, hipot tester, etc. A test of applying a specified AC or DC high voltage between the live part and the non-live part (usually the casing) of the …
Electrical safety testers (often referred to as hipot testers) are an integral part of electrical and electronic equipment manufacturing. The hipot tester takes its name from the high potential (high voltage) it generates to perform dielectric withstand voltage and insulation resistance tests. In addition to these tests, many hipot testers provide accurate low resistance measurements …
Hipot tester, also called ultra-high voltage hipot tester, portable AC and DC high voltage hipot tester, AC and DC ultra-high voltage hipot tester, AC and DC high voltage hipot tester. According to its function, it can be called electrical insulation strength tester, dielectric strength tester, etc. Hipot Tester working principle is: a voltage higher than …
