Calculation of the power consumed by the machine

Zaur asks:

Good time. Please tell me: the machine's tag indicates a current of 312A. How to calculate how many kilowatts it consumes per hour. If you can order the formula. Thanks in advance.

Hello! To begin with, let's clarify what the machine is powered by? From a three-phase 380V network? Further, a current of 312A is a very large current, did you accidentally make a mistake when you wrote down the numbers from the tag? Maybe 31.2A?
In any case, the total power of the three-phase circuit is calculated by the formula:
S = UlinearI * 1.73
or
S = UphaseI * 3
According to the first formula:
S = 380 * 312 * 1.73 = 205 108 W or 205.1 kW
According to the second formula, approximately the same comes out:
S = 220 * 312 * 3 = 205,920 W or 205.9 kW
Multiply by the number of hours, and you will find out how many kW / h it will wind. But this is a very high power, what is interesting about this machine you have?
We considered the issue of calculating power in detail in the article, I am attaching it, as you asked.
