Answer Posted / kj
The droop CT can be placed anywhere in the W phase. In
series star connected alternator it can be placed in the
output end, centre tap or neutral (star point end of the W
phase winding).
Remember it must be inserted as per the instructions as to
how many parallel coils pass through it and P1 must always
be in the correct direction. Always have P1 towards the
star point.
I have done this a number of times where the room around
the windings do not allow fitting elsewhere.

My question is whether bellow formula is correct to find bus size for 46kA for 0.5 second & what is RT in bellow formula. formula to calculate the size of busbar to withstand the thermal stresses due to currents with duration of 0.2 sec to 5 sec. Sp = RT( I x I x t) / K Where Sp – is the cross sectional area of bus bar in millimeters. I - is the value of AC fault current. t - is the operating time of disconnecting device in seconds. K – is the factor depending on the material of the conductor, insulation and initial and final temperature. Value of ‘k’ for copper is 143.
