In this lecture I have discussed the concept of Phantom loading Arrangement in energy meter. We use Phantom loading for calibration of energy meter because we never calibrate the energy meter at full load because at full load we waste a lot of energy in calibration. And we also saw the difference between Phantom loading and direct loading. And at the end we discuss Summary of this course.

I know that was wrong but I can't change this....after being uploaded the lesson.
Sir, is it possible can the disc moves in anticlockwise direction with positive supply due to some unknown error ? if Yes, which error will be happen ?
sir aapne Flux ka formula is lecture me galat bata diya. Please check f = Q/P =tan-1[ √3(w1-w2)/w1+w2] pf= cos-1(flux)

yes, you are right...it's wrong in summery part....But It's correct when I drived it in two wattmeter method part 3....so thanks for noticing this correction. It's good that you watch the lectures carefully.
sir D arsonaval galvanometer per ek video bna digiye na please

I've uploaded the preparation strategy for measurement course where I mentioned the syllabus of measurement for Electrical Engineering.... so remaining part of this course will be discussed accordingly.
sir would you cover measurement part of ECE?
