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 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.
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 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.
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.
