Useful And Essential Facts About Hipot Tester
High voltage or high potential test is what the phrase hipot test means. Dielectric withstand test is the other name for this test. It is an analysis of electrical parts. It is done purposely to check for suitability of the electrical insulation. Ensuring current leakage from one place to another within electrical devices does not exist is the goal the analysis is meant to achieve. This analysis is the exact contrary of continuity test. This is what Hipot tester are all about.
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 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.
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.
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.
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.
