Residual Current Calculation (I4)

The Power Meter module provides an output register labeled “I4” which holds the residual current value, derived from the three phase current measurements. As such, I4 represents the ground fault current, or the current flow in the neutral or ground conductor.

This quantity is only available when the meter's Volts Mode is set to 4-WIRE WYE. If the Power Meter module is set to any other Volts Mode, the I4 output will read NOT AVAILABLE.
