Abstract
Partial Stroke Testing (PST) equipment and methodologies provide PST data for an electromechanical valve, wherein power is withheld from the valve to trigger the vale to move away from a fully open position and power is subsequently applied to reinstate the fully open position immediately following detecting that the test valve has moved away from the fully open position. These operations are performed and monitored to determine whether they are completed within a prescribed period of time and associated data is generated that indicates a health of the valve subjected to the PST.
