Learn More About Dielectric Withstand Or Hipot Tester Procedures From An Industrial 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.

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 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.

At breakdown, electrical fields free bounded electrons. If applied electrical fields are sufficiently high, freed electrons from surrounding radiation might accelerate with velocities which could liberate further electrons during neutral atom molecule collision in a course termed avalanche breakdown. Avalanche Breakdowns take place somewhat quickly, in nanoseconds normally, resulting into an electrically conducive path structure and disrupting electron release throughout an object. For concrete materials, avalanche breakdown event rigorously debase, even demolish said materials insulating potential.

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.

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.

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.

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.
