The peak load of a transformer is the maximum power that the transformer can handle without exceeding its design limits. The peak load of a 5 MVA transformer would depend on the specific design of the transformer, including its voltage, current, and impedance ratings.
To determine the peak load of a 5 MVA transformer, you would need to know the voltage and current ratings of the transformer, as well as its impedance. The peak load of a transformer is equal to the product of the voltage and current ratings of the transformer, divided by the square root of the impedance.
For example, if a 5 MVA transformer has a voltage rating of 66 kV and a current rating of 1000 A, and the impedance of the transformer is 5%, the peak load of the transformer would be 5 MVA * 66 kV * 1000 A / sqrt(5%) = 3300 MW.
It is important to note that the peak load of a transformer is not the same as its continuous rating, which is the maximum power that the transformer can handle continuously without exceeding its design limits. The peak load of a transformer is typically higher than its continuous rating, and it should only be used for short periods of time.
