Mechanical overspeed protection systems use a weight on a spring of which the spring force is known. Two Woodridge 68 Educators Receive National Board Certification. in motor ships having steam turbo alternator, the over speed trip is controlled with the lubricating oil low pressure cut-out and the steam stop valve; whereas in few other ships the over speed trip is controlled using a system of levers and linkages that are connected by the turbine steam stop valve. Apart from over speed trips, permanent magnet alternators from engine camshafts along with rectifiers can also be used to prevent engine from racing at high speeds.
