The phrase hipot test means high potential or high voltage test. Another name used to refer to this test is dielectric withstand test. This is an analysis of electrical components that is done with the intention of checking for suitability of electrical insulation. The analysis is meant to ensure that there is no current leakage from one point to another in electrical devices. It is the opposite of continuity test. This is worth knowing about Hipot tester.
Hipot testing is supposed to be nondestructive to determine the adequacy of electrical insulation. The testing is high-voltage and it is applied to all electrical devices for a given period of time so as to ensure that the insulation is not marginal. The process involves the application of high amounts of voltage to the insulation.
Determining the availability of nicked or crushed insulation in a component is part of the goal of the process. Also, the process assists in identification of corrosive or conductive contaminants, stray wire strands, and braided shielding around conductors. By using hipot testing, one can easily identify terminal spacing problems and tolerance errors in cables. Compared to operating voltage, the voltage that is normally applied in this process is two times greater.
Hipot analyzers are the devices applied in Hipot testing. One side of the supply is normally connected to safety ground in a typical tester. The other side of the supply connects the conductor that has to be tested. Only two forms of contact to which the conductors can be linked exist in this arrangement. That is the voltage and ground.
In cases where there are 2 contacts that have to be connected, then one needs to be linked to the voltage whereas the other one is connected to ground. This type of connection is crucial as it guarantees that contacts get isolated from other kinds of contacts. If insulation between the two conductors is insufficient, then a small charge will flow between the two conductors when a massive voltage is passed through.
The flow of that tiny current is normally acceptable. However, a breakdown of air or solid insulation is supposed not to happen in any case. It is understood that any product is normally subjected to normal everyday transient over voltages. That is why high voltage is normally applied in these tests. Therefore, the product should remain safe and operational in event such differences in voltages happen during the day.
While doing this analysis, varying standards are normally observed. The voltage should be applied for varying amounts of time as required by different standards. The test needs to be continued for a one-minute duration. This requirement is under IEC 06950. A typical rule of thumb requires applying 110 to 120 percent of operational voltage of the product. This is plus 1000 volts for 1 to 2 seconds.
Specifications for the quantity of current which an individual should apply also exist. Many types of different testers which a person can purchase easily exist in the current market. Varying testers are designed for varying categories of products. Therefore, knowing the tester to apply for specific applications is vital.
