Turbine revolutions control
device
The device is an autonomous microprocessor system for measuring and
control of turbine revolutions in a Steam Power Plant. Constantly the revolution meter
measures and controls the revolutions of the turbine and the maximum and minimum
revolutions are controlled automatically. A visual message appears and a relay output is
activated at reaching the minimum or maximum speed.
