When supply side C.B. switched,at receiving end voltage
will not appear immediately."Wavefront" is formed.At left
of wavefront Vtg & current occurs,but at right vtg &
charging current is zero.
This wavefront travels from left to right with wave velocity
(v) which depend upon how fast inductance,capacitance reach
max.current & current .At no load capacitor charge through
inductance step by step.When line charged Vr=2Vs.When load
is connected this capacitor discharged,so vtg appear at
load.so that ferrenti not occurs at full load.

In Dyn11 power transformer if any one of the 3 phases connected to earth in star connected side then please explain effect of the current flow in delta connected side of transformer.(In this case if one phase is shorted to ground in star connected side then we observe the current flow in two phases only not three phases in delta connected primary side. Please explain why it is so?)
