VFD Input Current and Line Reactor Check

Drive input current from motor HP with efficiency, feeder at 125%, and the reactor call. 5 inputs, 3 outputs with grouped results.

Inputs

Drive

Driven motor nameplate HP (NEC Table 430.250, 460V).

Drive input voltage.

Typical 0.95 to 0.97.

Supply

High fault current argues for a reactor.

Drive nameplate kW for the reactor-ratio check.
