Useful Information Regarding Hipot Tester

By Diane Bailey


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 meant to be nondestructive and only to test the potency of electrical insulation. The testing uses high-voltage and is widely applied to all electrical gadgets for a certain period of time to be able to make sure that the insulating column is not marginal. The method involves applying the insulation with excessive amounts of voltage.

The purpose of the process is to determine if there is crushed or nicked insulation in a component. It also helps in identifying conductive or corrosive contaminants, braided shielding, and stray wire strands around conductors. Tolerance errors in cables and terminal spacing problems can also be identified easily using hipot testing. The voltage that is used in this process is usually two times greater than operating voltage.

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 case there are two contacts that need to be connected, then one has to be connected to the voltage while the other is connected to the ground. This kind of connection is important because it ensures that contacts are isolated from kinds of other contacts. If the insulation between the two conductors is inadequate, then a small current will flow between the conductors when a huge voltage is applied.

While the flow of a small current is normally acceptable, a breakdown of air or solid insulation is not expected in whatever case. Excessive voltage is generally used in these assessments due to the fact that any electrical product is subjected to regular day-to-day transient over voltages. In the event that such variations in voltages take place at some point of the day, the product should be able to remain safe and working.

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.
