Woodward 8272-781 Real Power Sensor ORIGINAL

The Woodward 8272-781 is a real-power sensing module designed for Woodward generator and turbine control systems. It acquires three-phase current and voltage signals from current transformers (CT) and potential transformers (PT) on the power bus, computes real active power, and delivers proportional analog load signals to governor controllers for generator load-sharing, droop control and synchronizer functions.
