The corresponding volt drops are: \ 1, 000/ \ 1, 000/ = 72 X 0-02+ 113 X 0-035 = 1- 44 + 3-95 Total drop in line due to reaction ... Most of the power load in a fairly large factory is three-phase, while heating, lighting, and very small motors are single-phase. A main ... bus-bars are connected to the cable through an oil circuit -breaker, and energy meters are interposed as shown in the diagram. ... Many large factories are supplied directly by an 11kV, 6-6-kV, or 3-3-kV main distribution line.
