Transformer Calculation

Good ... the problem is this: I need to calculate a three-phase transformer in kva for a crusher. It consists of several transformers that will work all at the same time. The biggest load is a 40 hp engine. The problem is that I only have the powers in hp and they still don't give me the other engines ... so I would like someone to help me indicating how to do the calculation in kva from the powers of several engines in hp? ... thanks in advance to the forum ...

The apparent power in a three-phase motor is calculated, with the voltage and current:
1.73 * V * I.

The factor 1.73 is the product of dividing the sum of the powers of the 3 phases in square root of 3.
And the square root of 3 is a product of the 120 ° offset between the phases.

Hello, I hope the information that I will give you this formula will help you, it is only to calculate the drop that your circuit would have, I will also add the description
Vd = voltage drop
I = current in conductor (amperes)
L = one-wayLength of circuit (feet)
Cm = sectionarea of driver croos
K = recistance in ohms
copper = 12.9
aluminum = 21.2
Vd = 1.73kxLx1 all divided by CM
Cm = 1.73kxLxI all divided by Vd
I hope you serve the formulas and greetings
