Dielectric Strength or Hi Pot testings are completed by applying massive voltage against testing wire and ground, usually locomotive chassis. On the off chance that excess current spills or if a current arc happens, test show failure. Insulation Resistance tests give numbers showing resistance insulation. Data on how hipot testers function are found below.
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 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.
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 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.
Though, commonly, HiPot analyzer being utilized for Di electric Quality test would satisfy usage towards Insulation Resistance analyzation. Particular terminology utilization would truly rely upon trade you are working, managing. In the event that it truly matters, you have to read given methodology label 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.
