Steam Turbine | List of Available Signals

At acquisition, the following signals are made available by the sensors. Only signals from subsystems common to both turbine generators and signals from the primary turbine generator are listed. The names of signals from the secondary turbine generator are obtained by adding a suffix “_s” to the names of signals from the primary turbine generator.
