The distribution primary substation may be modelled as a single line diagram below. ... Mathematical model of a main transformer with OLTC and bus capacitor The following symbols in the above diagram represent: VI = main transformer primary (132kV) bus voltage ... From the 11kV source fault level, it is noticed that possible change in busbar voltage (0.02p.u.) for switching in/out of a capacitor will at 480.
