Q/Derive from Figure (1) the final equation and law (V4,V5) by assuming given data , the equivalent circuit for a 5- disc string . Let us suppose that self capacitance of each disc is C. Let us further assume that shunt capacitance C, is some fraction K of self capacitance i.e. , C, = KC. Starting from the cross - arm or tower, the volt age across each unit is V1 , V2 ,V3 , V4 and V5 , respectively as shown . Applying Kirchhoff's current law to node A, we get, 不 Vz Cニ 不I V5 Ci is E (fiz 1)
