9. A large building is taking 3-phase supply from utility at LV i.e. 400 V. After adding capacitors at the intake point of the electrical installation and the power factor at the intake point has been improved from 0.6 lag to 0.9 lag. As a result, the electrical distribution loss in the building is reduced approximately by: S Cap's Q = (0-jx) var. Q = +ve.
