You may draw vector diagram considering the resistance of line
is very small and capacitance and inductance large. In low
load currents the effect of inductive drop is almost nil where
as the capacitive MVAr generation is large. This is because,
the capacitance is in shunt of the line (parallel to line)
where as the inductance is in series with the line. As the
load increases, the VAr iconsumed in the inductive drop. ( I *
XL drop and var consumption is I^2*XL) whereas the the
capacitive effect is constant whether load or no load. Hence,
as the load increases, the inductive drop takes over and as a
result, there is no ferranti effect. (You can draw vector
diagram for low loads and hi loads)

Hi, I've just got into my electrical engineering course and I need some help with a question of mine here. During a site visit, we were shown a main LT panel which has switchgears, ammeters and different kinds of relays and the distribution network from that panel. In the main LT panel I've noted down the current readings as Ir - 163A, Iy - 150A and Ib - 147A. The Line to Line voltage is 415 V at 50 Hz and Line to Neutral voltage is 230V at 50 Hz. From the above details, how would I calculate the kVA rating of transformer? The primary side voltage of the transformer is 11 kV and the secondary side voltage is 415V and the frequency is 50 Hz.
