how can i design a APFCR panel?
please explain with example..

Answer Posted / himadri

For Designing the APFC we have to know the desire power factor of system and present power factor value.
After that we have to draw power triangle where kw value will be same. Form power triangle we can find the extra kVAR requirement to achieve the desire power factor.
That extra kVAR will be supply by capacitor bank. Then we have to fine out the capacitance value which will supply the extra kVAR.

I have a drawing of a wound rotor induction motor for a crane. This crane motor has 5 forward speeds & 5 reverse speed implemented of course with different amount of resistance for each speed setting selected. What has got me scratching around is the fact that 8 of the 10 speed selections switch in uneven (unbalanced) amounts of resistances on each of the 3 connections to the motor's rotor.Can this be possible? I would have assumed this would produce unbalanced rotor currents and therefore vibration in the motor. I would greatly appreciate anyone's comments on this. Many thanks, Confused.
