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.
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 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.
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.
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.
