For power factor correction, synchronous motors operate at no-load and greatly over-excited fields.
Last Answer : The standard full-load power factor ratings for synchronous motors are unity or 0.8 leading.
Description : Draw and explain bulk correction method for power factor & control.
Last Answer : Bulk correction method for power factor & control: i) Here individual starter controls the capacitors located at distribution panel. ii) Centralized compensation is employed in large industrial plants where many ... capacitor units in steps to maintain P.F. more than preset limit (0.95).
