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/?.
transformer action doesn't depend on power factor that is why we indicate its rating in KVA
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.
Sounds like the wrong size fuse protection was used. The transformer should be protected to its kva capacity.

How to compute for the size of wire in the primary side of 2500 kVA transformer 34.5kV
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/?.
200 and 100
The 3 kVA transformer will weigh double the 1.5 kVA transformer.
The kW rating of a transformer can be calculated by multiplying the kVA rating by the power factor. For example, if the power factor is 0.8, then the kW rating of a 100 kVA transformer would be 80 kW. You can also use the formula: kW = kVA x power factor.
In 1600 kva transformer we provide NGR (Neutral grounding resistance)
Depends on the kva rating of the devices to be tested using a transformer.

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.
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.
The result is that the transformer runs cool and contented. The '250 KVA' rating on the transformer is its maximum ability to transfer power from its input to its output without overheating, NOT an amount of power always running through it. If the 3 KVA load happens to be the only thing connected to the transformer at the time, then only 3 KVA flows into the transformer from the primary line, and only 3 KVA leaves the transformer secondary.
