Hi all. I'm a mechanical engineer by training and a manufacturing engineer by trade. I currently find myself in the position of being asked to fill out a spreadsheet containing, amongst other things, machine tools' power consumption in kVA. Occasionally an OEM will be helpful and provide this directly in the datasheet but more often I'm given volts, frequency and phase. How can I reliably approximate a value for kVA given these variables or what else do I need to know in order to calculate? Many thanks!
