The adjustment of position of shading bands, in an energy meter is done to provide______________?
Correct answer: A. friction compensation
- A. friction compensation
- B. creep compensation
- C. braking torque
- D. none of the above
Explanation
The shading bands on an energy meter adjust the phase and magnitude of the shunt-magnet flux at light load, producing a compensating torque for friction. Creep is controlled by methods such as holes or slots in the disc and is not the purpose of band-position adjustment.
