What Is HIPOT Testing?

It is essential to test Hipot to ensure that the current flows smoothly from one stage to another. The test verifies the cable’s integrity and its ability to withstand a given amount of electricity at high voltages. Testing guarantees the durability of cable assemblies or wire harnesses, proving life-threatening if a malfunction has occurred. All electrical circuits’ protection and efficiency are assured by a good separation between the parts of a circuit.

 

The Hipot Tester is the Reverse of a Continuity Check

The continuity test quickly tests the security of current flows from one stage to another. On the other hand, Hipot Test ensures that the current will not flow from one stage to another and that the voltage will switch up high to ensure that no current will flow. A non-destructive test aimed at testing the amount of electrical insulation is the HiPot Test. In other words, the test enables technicians to assess whether the insulation can control transient over-voltages.

 

Measuring Electric Insulation

The Hipot test’s significance is that the electrical insulation level of the individual system or assembly is calculated. If the insulation can withstand any transient over-voltages, the ‘press’ causes electromotive charges to travel in a wire or other electrical conductor. To ensure that the insulation complies with safety and quality requirements, electrical insulation is exposed to high voltage for an extended period.

 

Identifying Insulation Issues

The hi-pot testing equipment also helps detect insulation problems by exposing the electrical insulation to intermittent over-voltages. Checking for these problems is essential. Often, insulation is subject to volatile environments or conditions that can affect the device’s efficiency. Electronic harnesses and cable assemblies can experience electrical insulation issues with braided shielding, stray wire strands, tolerance errors, corrosive contaminants, and even terminal spacing problems. It can also be used to find cuts in the insulation and nicked or crushed insulation.

 

Detecting Production Units

During the manufacturing process, Hipot checks may also be conducted on production lines. Testing is intended to detect whether the production device’s assembly is similar to that of the type testers. It is possible to detect potential problems unintentionally introduced or added during production, such as creepage or improper clearance distances, a pinhole insulation defect, and the position of an expanded solder footprint.

 

How Hipot Tests Work?

For safety and quality purposes, the Hipot tester is appropriate to test an electronic system’s stress. It tests under high voltage that there is no failure or perforation and that insulation distances are respected on the line and in the air. Between mutually insulated sections of a part or energized parts and electrical soil, tests can be conducted. In any case, an electric current will pass between two points during testing.

The test usually works by connecting one end of the supply to the ground and the other end to the tested conductor. It is possible to link conductors either to a high voltage source or to the environment. Only ensure that your contact for high pot tester is separated from any other contacts. Depending on the tester’s size, the Hipot testers will measure from 5k volts to 400k volts.
