Dielectric Withstand or hipot testing is done by applying high voltage between wire being tested and ground, presumably locomotive chassis. If excess current leakage or if an arc occurs, test fails. Insulation Resistance testing provides numerical value indicating resistance insulation. Information on how hipot testers work can be read 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 presents maximum electrical field that pure material may withstand underneath ideal setting without tearing down or without experiencing failure with its insulating properties. Theoretical dielectric strength is material intrinsic property on bulk material and independent configuration material or electrodes with which field is put to use. This inherent dielectric withstand corresponds what is being measured using untouched materials under controlled laboratory settings.
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.
Regarding insulation di electric testing variations, none exists. There exists no significant dissimilarity between dielectric testing and insulation. Di electric strength value basically shows how adept an electrically conducive object. Now about testing, frequency measuring volts must be verified by specific volt type insulating objects would receive during its operation period. Which simply means one must not DC withstand measure components that would be employed for AC 5060 Hertz purposes.
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.
An emphasis on these tests interchangeability would trivial because, at the end of the day, most insulated materials go through both as it unwise generally to pigeon hole your substance product into using only one frequency, electrical transmission when most cases it will work for both assuming they have same amount. Using 48v DC system, generally using materials with secondary rating around 600v ac should suffice. Ultimately as long as one does not fail hipot, everyones happy regardless of insulated matter used.
