Electronic overspeed protection consists of a gear or other measuring surface, speed sensors and a measuring system with trip logic and relay outputs. The speed sensors look at the measuring surface and give a sine or square wave signal, which the measuring system sees as pulses. Trip valve packing is essentially a filter that will trap any contaminants between the trip valve and the packing which can prevent the trip valve from closing. This is normally accomplished with dump valves that re-route the feed stream from the turbine inlet directly into the condensers. Learn more about the used cookie. As the speed of the engine crosses the pre-set speed, the voltage automatically increases, making the governor to reduce the fuel supply to the engine cylinder and lowering its speed.
