Here are some useful 3 Phase fomulae.
1)
kW = kVA x power factor
2)
kW = (hp x 746) / (1000 x efficiency)
3)
kW = (line amps x line volts x 1.73 x pf) / 1000
4)
kVA = kW / pf
5)
kVA = (hp x 746) / (1000 x efficiency x pf)
6)
kVA = (line amps x line volts x 1.73) / 1000
7)
Line amps = (kW...
You should never, ever rely on software only for safety interlocking, especially if human operators could be endangered by the system being controlled. Always use an approved 'stand alone' system.
