The V stands for volts and A is amps. If for example you have a 12kVA device and are running off a voltage of 120 volts then Amps = 12000/120 = 100. You then use the calculated amps in a wire size table to get the correct size.
Wire sizing of a feed conductor is based on the amperage that a device draws. To calculate amperage from KVA a voltage of the supply has to be stated. Without this voltage and whether the transformer is single or three phase an answer can not be given.
250 kVA generators come in different voltage settings and this information is needed before a wire size can be given
A 10 mm cable is most commonly used for a 500 KVA transformer, 240 volt, 3 phrase. The size of the wire that is used in a transformer is based on the voltage.
The size of grounding wire is based on the amperage output of the transformer. The voltage of the transformer needs to be stated. Without this voltage a calculation can not be made. Amps = Watts/Volts = 30000/?.
It depends totally on the voltage used.

How to compute for the size of wire in the primary side of 2500 kVA transformer 34.5kV
To answer this question a voltage must be given to find the current output. Also whether the generator is three phase or single phase.
A 10 mm cable is most commonly used for a 500 KVA transformer, 240 volt, 3 phrase. The size of the wire that is used in a transformer is based on the voltage.
For a 9.5 kVA load, you would need around a 40 amp circuit. Assuming a typical voltage of 240V for this load, you would need at least 8-gauge wire to safely handle the current. It is always best to consult with a qualified electrician to ensure the correct wire size for your specific installation.
The size of grounding wire is based on the amperage output of the transformer. The voltage of the transformer needs to be stated. Without this voltage a calculation can not be made. Amps = Watts/Volts = 30000/?.
3r x 300sq.mm Al. ar UG cable <<>> Wiring is sized by the amperage that is used by the load. The formula for amps is I = W/E. Amps = Watts (or VA)/Volts. As you can see an answer can not be given unless a voltage is stated. The lower the primary voltage the larger the amperage will be and likewise the larger the wire size will be.
If you multiply kVA by Power Factor (Ranges from zero to one) you get watts which is effective power.
A motor can be reckoned at 1.6 kVA per horse-power, so on a 415 v 3-phase suppy the current for 20 HP would be 45 amps. For continuous use the wire size should be 25 mm2
There is insufficient information in the question to properly answer it. While you specified the primary voltage, 34.5 Kv, you did not specify the current or the KVa. Please restate the question.
A transformer has separate ratings for maximum voltage and maximum current. Both limits must be observed. The maximum voltage is set by the magnetic flux density in the core, while the current limit is set by the size of the wire used in the primary and secondary windings. Multiplying the two together gives the VA or kVA rating.
