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 reason for the process is to detect the presence of nicked or crushed insulation in a device. It also enables the identification corrosive or conductive contaminants, stray wire strands, and braided defensive around conductors. Tolerance mistakes in cables and troubles in terminal spacing can also be diagnosed easily by using hipot testing. Voltage that is used on this system is commonly two times more than the operating voltage.
Hipot testing is usually conducted using hipot analyzers. A typical tester usually connects one side of the supply to safety ground. The second side of the supply gets connected to the conductor that need to be tested. In this arrangement, there are only two kinds of contact to which conductors can be connected, that is, the ground and voltage.
In the situation there exist two contacts for which connection is needed, then a person must connect one to the ground while the other one to the voltage. This type of connection is vital. It makes sure that contacts are isolated from other forms of contacts. A small current will flow from one conductor to the other when a massive voltage is applied when the insulation placed between the two conductors is not adequate.
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 different standards that are usually observed when conducting this analysis. The various standards require the voltage to be applied for different amounts of time. Under the IEC 06950, the analysis is supposed to be continued continuously for a duration of one minute. However, a typical rule of thumb is to apply 110 to 120 percent of operating voltage of the product plus 1000 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.
