If Dg set is running parallel with grid we can adjust the
power factor through excitation, but if it is running in
ideal mode we cant adjust the power factor through
excitation, so we need capacitor bank at that time.

we all know that in transformer, voltage and current are inversely related i.e. Vp/Vs= Is/Ip....so in standard CT..we have a ratio of 200/5...that means our voltage should increase by ratio of 40..althoug that is not the case...because that requires high insulation level.and pratically not feasible......can anybody clarify my ques.......thanx
