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.
High Pots could be AC, DC and conducted sporadically, or at final assembly line stage, etc. Stress assessment results, in general, illustrates Pass Fail basing on current leak. For several systems, this method may bear out risks. Testing medium volt wire might also pose dangers.
Dielectric quality presents peak electric field that raw material may withstand under perfect conditions without tearing apart or without encountering insulating properties breakdown. Theoretical dielectric quality is material natural property on mass and separate system material or an electrode within field is connected. This natural dielectric withstand illustrates what might be estimated utilizing raw materials under perfect laboratory conditions.
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 difference between insulation and dielectric testing, none exists. There should be no difference between insulation versus dielectric testing. Dielectrical strength simply shows how well insulator material. Now regarding testing, frequency test voltage should be determined by what voltage type insulating substance will expect during its operational life. Which means you should not DC withstand testing component that will be used for AC 5060 Hz applications.
While those above are simply two separate as well as very unlike engineering methods, those two are casually used around interchangeably within electrical engineering industry. So one cannot simply depend on those terms accurately describing what is currently being tested along with laboratory performance. For instance, in Handy Guide Electrical Tests, wherein Dielectric Tests is their defined an insulation opposing attribute test HiPot test mix.
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 test will show DC most of the time. Di electric withstand test will commonly be AC yet can be DC. When one studies AC DC removal as one investigates similar subjects, previous experiments regarding above topic were conducted by research engineers. Final results show both are still required since they offer very distinct information.
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.
