Friction Compensation & Creeping Error

In this lesson I have discussed friction compensation and creeping error. Generally fractional error is introduced at very light load condition in the energy meter. To remove fractional error we use some technique that is called friction compensation of energy meter. We use shading ring to remove frictional error by increasing the value of driving torque. And creeping error is introduced due to over compensation of friction error. There is two method to remove creeping error. One is fix the iron piece at the edge of aluminium disc and another is drill holes at diametrically opposite of AL disc.

sir hamlog ke school me trigonometry start ho gaya hi sabse pahle aur ye range domain sab nahi parhaya gaya hi. kya ye imp. hi
really awesome especially for shading ring concept.
sir in this video you mention slow rotation below the word creeping error . don't you think it should be fast rotation ??

I am just telling that the meaning of creeping word is slow rotation.
hello sir, how many part will be there to complete Electrical Measurement & Instrumentation ???
