Dielectric Strength or Hi Pot testings are completed by applying massive voltage against testing wire and ground, usually locomotive chassis. On the off chance that excess current spills or if a current arc happens, test show failure. Insulation Resistance tests give numbers showing resistance insulation. Data on how hipot testers function are found below.
Hi Pot can either be AC DC, done occasionally or at assembly line end among others. Stress test result commonly indicates Pass Fail in view of current leak. For a few structures, this may demonstrate risk. Testing median voltage cable might likewise demonstrate risk.
Dielectric strength illustrates max electric field pure substances could endure under optimal conditions without tearing or without showing breakdown of its insulating attributes. Theoretical dielectric withstand is a natural object attribute on raw material and autonomously designed material or electrodes to which electrical field is flowed. This innate dielectric withstand communicate data on what needs measuring using raw materials subjected upon optimal laboratory setting.
On breakdowns, electric field liberates bound electrons. In the event that connected electric field is adequately high, liberated electrons from environment radiation may wind up with quickened speeds that can free more electrons amid crashes with neutral molecules, atoms in process termed avalanche breakdown. Breakdown happens unexpectedly, n nanoseconds commonly, bringing about an electrically conductive way path and unexpected material discharge. For strong materials, breakdowns corrupts, even removes, materials insulating ability.
With respect to insulations and dielectric testings differences, none exists. Contrast between insulation and di electric testing does not matter. Dielectric quality basically demonstrates how well an insulator is. About testing, frequency test ought to be controlled by what voltage insulating substance should expect amid its functional period. Which implies you ought keep from DC quality testing aspects that will be utilized for AC 50 or 60 Hertz applications.
Whilst they are only two particular and altogether different techniques, these terms are irresponsibly tossed around reciprocally in trade. So you cannot without much stretch depend on those names precisely portraying what is being examined closely by way test was done. For instance, in Practice manual Dielectric Tests, wherein Di electric Tests within definition is mix of HiPot tests Insulation Resistance tests.
Though, commonly, HiPot analyzer being utilized for Di electric Quality test would satisfy usage towards Insulation Resistance analyzation. Particular terminology utilization would truly rely upon trade you are working, managing. In the event that it truly matters, you have to read given methodology label itself.
Insulation Resistance analyzation would dependably indicate DC. Di electric Quality test will typically be AC, however, could be DC. In the event that one checks whether one or the other could be skipped as they examine same things, investigations were done previously. Both are required as they give distinctive information as their final data.
A highlight unto interchangeability of these voltage tests is insignificant since all things considered, almost all manufactured insulated products undergo both tests since pigeon holing manufactured product into utilizing only one type of voltage frequency or electric transmission will always work for either provided they both have the same amount. Applying a 48v DC system with 650v AC secondary rated materials should be enough. Basically, not failing hipot would suffice regardless of insulating matter applied with.
