Hi,
Mechanical guy here with little electrical knowledge.
I have the amps reading on each phase of a 50hp rated motor. The line voltage is know to be 460V. Don't know if it is a Y or Delta circuit (don't think it makes any difference).
Is the following an acceptable way to estimate the power usage of the drive?
Ip1 = 27
Ip2 = 28
Ip3 = 27
P drive = avg(27,28,27) * 460V * sqrt3 = 21.78 kW
Or am I way out in the left field?
Many thanks
