May I ask the experts, for a high - voltage motor with a voltage of 10 kV and a power of 1,120 kW, how much electricity does it consume in one hour? I'm a newbie, please don't spray me!

Electricity Friend A: This refers to the output power on the shaft of the rated motor. If it is at full load, the actual power is not exactly the same as the rated power. If it is not at full load, the power is smaller than the rated value. If you want to calculate the actual power consumption: voltage * current * 1.73 = actual wattage. According to the rule that 1,000 watts consume 1 kilowatt-hour of electricity per hour, it is approximately around 1,120 kilowatt-hours.
Electricity Friend B: The power consumption of an electric motor is determined by the load. You need to actually measure the active power for calculation or estimate it by measuring the actual voltage and current (the closer the motor is to full load, the relatively higher the power factor is) to calculate the power consumption. The rated power of an electric motor refers to how much power it can output, that is to say, the rated power refers to the load-carrying capacity, rather than the actual power consumption.
Electricity Friend C: You can roughly calculate it like this: P = 1.73 * U * I * power factor, and then convert it into kilowatt-hours, which is equal to the number of degrees of electricity consumption.
