Answer / vikramvijayk
Dear Mr.Nagaachi,
The answer is 100KVA(losses are negiable) because In an
transformer the KVA must be same to both side(PY&SY).

Answer / vikas
As the xmer is havin its rating in kva so it depends only on voltage and current so if voltage increases thn current decreases and vice versa so if primary voltage is increased so its current decreases nd vice versa. So if secondary voltage is 11kv thn current in secondary will increase so i think kva will remain same.

The full load secondary current of 11/0.433 kV, 100 kVA
trafo is 140 Amps. This much current only can flow on the
secondary. The secondary voltage when 433 V is fed to the
primary is 17 Volts (433x433/1000). Hence it would give
about 4 kVA. (1.732x17x140/1000)

Answer / nagaachi
IT S ME WHO THE QUESTIAN IS ASKED,
MY IDEA IS THAT,
100KVA=ROOT3*11*5.2=ROOT3*.433*133
IF IT HOLD GOOD THE RELATION 5.2(root3*voltage)
thus we can get the answer as 5.2(root3*.433)=3.89KVA
PLEASE HELP ME GETTING THE SOLUTION
THIS QUESTIAN TEASING ME

Answer / s.arul
Dear sir,
transformer only changed the voltage & current
rating. so not changed the KVA.
KVA = KV * A
SO, PRIMARY SIDE
100 = 11 * A
A = 100/11 SO CURRENT = 9.09 AMPS
SECONDRY SIDE
100 = .433* A
A = 100/.433 SO CURRENT = 230.95 AMPS

Given a collection of points P in the plane, a 1-set is a point in P that can be separated from the rest by a line; i.e. the point lies on one side of the line while the others lie on the other side. The number of 1-sets of P is denoted by n1(P). The maximum value of n1(P) over all configurations P of 19 points in the plane is 18
