Abstracts: As we know, the world today is unimaginable without electricity. Large scale electrical energy production largely depends on the use of turbines. Nearly all of the world's power that is supplied to a major grid is produced by turbines. A turbine is a simple device with few parts that uses flowing fluids (liquids or gases) to produce electrical energy. Fluid is forced across blades mounted on a shaft, which causes the shaft to turn. The energy produced from the shaft rotation is collected by a generator which converts the motion to electrical energy using a magnetic field. The controlling of the turbines was done initially by mechanical governors. Now, with the technological advancement, they are replaced by the electronic governors. Steam turbine governing is the procedure of controlling the flow rate of steam into a steam turbine so as to maintain its speed of rotation as constant This project is dedicated to the study and design of a Current to Pressure Converter, which converts the electric signal from the governor to the hydraulic signal, which further controls the servomechanism. It forms an integral part of the controlling. CPC quickly and accurately converts the input signal into a proportional output pressure. This is important as the turbine should function as expected in load variant conditions and also stop in abnormal conditions.
