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 testing is normally carried out by use of hipot analyzers. A normal tester usually connects one side to earth while the second part of the tester is connected to conductor that needs to be analyzed. In the arrangement, there are two contact points to which conductors may be connected, the ground and voltage.
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.
Even though the flow of such a small current is usually acceptable, a breakdown of solid or air insulation is not supposed to occur in any case. High voltage is usually used in these tests because it is believed that any product is usually subjected to normal day-to-day transient over voltages. As such, in case such variations in voltages occur during the day, the product is supposed to remain operational and safe.
There are several requirements that are normally checked while carrying out this evaluation. The various requirements need the voltage to get applied for a distinct amount of time. Under IEC 06950 standards, the analysis is meant to be carried out continuously for a period of one minute. Nevertheless, a typical rule is to use 110-220 percent of working voltage of the product plus a thousand volts for 1 to 2 seconds.
There also are specifications for the quantity of current that is supposed to be applied. As of now, there are several distinct varieties of testers available in the market for people to purchase. Different types of testers are designed for different categories of products. It is therefore critical to know which tester to apply for certain applications.
