The term "hipot" is an abbreviation for high potential, meaning a high potential for high voltage. It is an essential form of electrical testing that is crucial to ensuring successful operation of electronics. Hipot testers are different than other testers in that they aren’t looking to identify good connections. Rather, hipot testers – or high voltage testers - are looking for what is termed “good isolation.” They want to be sure that no current, or no electricity, is flowing between points. If the hipot testers determine that there is indeed good isolation, then the quality and safety of the electrical component is essentially guaranteed.
The value in using hipot testers is that any problems or issues can be detected such as frayed wiring, space problems or other instances that would cause current to flow. There are a few common types of hipot testing, one of which is dielectric testing. One type of dielectric testing is to push the limits and determine exactly how much voltage the equipment under test can withstand before failing. Another type of dielectric testing is to set a particular level of voltage for a predetermined amount of time. The test here is to see the length of time the item under test can withstand a particular voltage setting.
