Discover More About Hipot Testers, Dielectric Strength Tests And Their Similarities And Dissimilarities

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.

In breakdown, electric field effectively frees bounded electrons. When applied electrical field is high, free electrons coming from background current radiation may be accelerated with velocities that may liberate additional bounded electrons upon meeting neutral atomic particles, molecules within avalanche breakdown. Breakdowns occur quite suddenly, typically nanoseconds, causing an electrical conduction path formation and disruptive discharge through material. Towards solid materials, breakdowns severely degrades, even neutralizing, its capability to insulate.

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 they are just two separate and very different procedures, these terms are wildly thrown around interchangeably in electrical industry. So you cannot easily rely on those names accurately describe what is being tested alongside how test was performed. For example, in Practical Guide Di electric Tests, where Di electric Tests in their definition is an Insulation Resistance tests HiPot tests combination.

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 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.
