Real Power Sensor (RPS)
The Real Power Sensor is used to sense the real power being produced by a
generator, or flowing through a tie line. Woodward Real Power Sensors sense
three phase voltages and three phase currents. The RPS compares each
phase’s voltage to current relationship and develops a 4–20 mA output
proportional to real power.
The RPS provided with a standard 5009 system accepts only 0–5 A and has a
kW and VAR readout. The “KW Readout” terminals provide a 4–20 mA signal
proportional to real power, which is used by, and compatible with, the 5009
control.
