Reverse power operation

The importance of the correct operation of the counter extends beyond mere counting
operations. One additional feature of the control is distinct "reverse power" operations
depending on power flow direction. In addition to normal configurations of "block" or
"ignore" during automatic reverse power detection, the control may be configured to
"regulate in reverse direction" or "return to the neutral position." The control includes a
power direction function for detecting the reversal of power flow in the regulator or
transformer. The active power direction is based on the flow of real power and is not
confused by reactive power flow in either direction.
