Single phase motors are desined for work only in single
phase supply , that is It conist of two windings. starting
winding and running winding.They are arranged in 90
electrical degree degree phase shift. And the input cables
are only two for phase and neutral.But in the case of Three
phase motor consist of Three windings they are arranged
in 120 electrical degree phase shift.and 6 No.s of input
cable for connect either star or delta.

in the directional overcurrent and earthfault protection,normally we are setting the angle 45 deg lead for phase fault overcurrent and -45 deg lead for earthfault fro forward direction.but both the fault are operating on the same angle region only.why?how the relay will response?

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.
