About video :
In this video we are doing Meggar Insulation test of 761 KVA 3 Phase generator alternator. Complete procedure of Meggar using , Continuity test and insulation test.
The Megger insulation tester is a small, portable instrument that gives you a direct reading of insulation resistance in ohms or megohms. For good insulation, the resistance usually reads in the megohm range.
What is a good Megger test result?
Anything reading between 2 megohms and 1000 megohms is usually considered a good reading, unless other problems have been noted. Anything less than 2 megohms indicates an insulation problem.
What is difference between Megger test and insulation resistance test?
An insulation tester performs the basic measuring function a megohmmeter does-measuring very high resistance values by sending a high voltage signal into the object being tested-and it often does much more; it usually performs more functions, including more complex testing and recording of measurements.
What is the difference between megger and ohmmeter?
Impedence of insulation is very high. A megger is specifically designed to accurately measure high impedences. An ordinary multimeter is designed to measure lower, more finite impedences. Therefore a megger is more accurate for the application.

Thank you for your work.
thank you for knowledge i'm inspire with this video
Good work Sir 😊
Hi sir thank you very much for providing practical knowledge 🙏🙏🙏
nice sir
Keep it up bro
asalamualaikum,,,if you want to test the insulation resistance on the alternator,stator and rotor,do you have to release the stroom on the baterry please enlighten me,,
Please explain what a result of
👍👍
Good.. but i can hear a goat eating at the back ground... Haha
Why the one cable has a higher resistance like that!
sir in motor three winding each winding two terminals so total 6 terminals.
i think you forget to short rectifier before taking merger.
Sir humble request for generator testing commission step by step explain and procedure please
