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

By Carl Hughes


Dielectric Strength or hipot test procedure is conducted by generating high voltage power between wire tested to the ground, most likely locomotive chassis. When overloaded current leaks or when an arc transpires, test fall short. Insulation Resistance measuring usually presents numerical values on resistance insulation indication. Facts on hipot testers measuring work are discussed.

High Pot can be AC or DC and done periodically, or at production line end, etc. Stress test result typically shows Pass Fail based on leakage current. For some systems, this may prove dangerous. Testing Medium Voltage Cable may also prove risky.

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.

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.

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, generally, HiPot tester currently used unto Dielectric Strength value test will suit utilization towards Insulation Resistance experiments. Precise term usage will heavily depend on firm you work for, deal with. As a precautionary measure, you must always read set method information yourself.

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 accentuation on the two tests interchangeability will provide insignificance as most insulated substance are analyzed by the two tests as it hasty to categorizing your substance item based on just a single frequency, electrical current transmission when generally it works for both given they have same amounts. Utilizing 48v DC framework, for most part utilizing materials with optional rating around 600v air conditioning should get job done. As item does not come up short hipot, everyones content paying no attention to insulated item utilized.
