Important Facts On Dielectric Strength Or Hipot Tester Measures From An Electrical Engineering Perspective


by Carl Hughes


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 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.

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.

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.

Whereas, typically, HiPot tester being used for Di electric Strength Withstand test would suit utilization for an Insulation Resistance test. Specific terminology used would really depend on company you are working, dealing with. If it really matters, you need to read given procedure description itself.

An Insulation Resistance tests would always show DC. Di electric Strength tests would usually AC but could be DC. If one see if one other could go through elimination as they investigate similar things, electrical experiments were done before. Conclusion was that they are both needed as they provide different data as their results.

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.
