Abstract
Apparatus and a method for protecting a steam turbine from damage due to moisture are disclosed. The temperature and pressure of the incoming steam are monitored to determine if sufficient superheat energy is available to assure that the steam will flow through the turbine in the gaseous phase. The same inputs may be utilized to determine under and over pressure steam conditions. Once a fault condition is detected, operation of the turbine will be automatically interrupted.
