11/.433KV, 100KVA TRANSFORMER is supplied with .433KV AT ITS PRIMARY. HOW MUCH KVA IT CAN SUPPLY..

Answer / meenakshi

without knowing the current rating it is not possible to
find the kva.if 0.433kv is given at primary, u can find
only the secondary voltage vid the help of turns ratio.so
its not possible to find.

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).

11/.433KV, 100KVA TRANSFORMER is supplied with .433KV AT ITS PRIMARY. HOW MUCH KVA IT CAN SUPPLY..

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.

11/.433KV, 100KVA TRANSFORMER is supplied with .433KV AT ITS PRIMARY. HOW MUCH KVA IT CAN SUPPLY..

Answer / pichumani

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)

11/.433KV, 100KVA TRANSFORMER is supplied with .433KV AT ITS PRIMARY. HOW MUCH KVA IT CAN SUPPLY..

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

Answer / k suresh

I THINK IT IS GOOD QUESTION. THERE IS NO CHANGES IN RATING
(KVA),VOLTAGE AND CURRENT WILL CHANE DEPEND UP THE T/F
WINDING TUNERS (N).

11/.433KV, 100KVA TRANSFORMER is supplied with .433KV AT ITS PRIMARY. HOW MUCH KVA IT CAN SUPPLY..

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
