Series Capacitor It is connected in series capacitor to compensate the inductive reactance of line. This reduces the transfer reactance between the buses to which the line is connected. It increases maximum power that can be transmitted and reduces reactive power loss. The reactive power produced by the series capacitor increases with increase in power

Primary function of the pressure control valves is to match the flow of fluid through the regulator to the demand for fluid placed upon the system. If the load flow decreases, then the regulator flow must decrease also. If the load flow increases, then the regulator flow must increase in order to keep the controlled

A load cell is an electromechanical transducer that converts load acting on it into an analog electrical signal. Strain Gauge Load cell provide accurate measurement of compressive and tensile loads. Load cells commonly function by utilizing an internal strain gauge that measure deflection. Because the modulus of elasticity of a load cell is constant the

Intro – Computer Control of Power System Operation in plants with automated computer control of power system work mainly in a central control room. In olden plants, the controls for the equipment are not centralized and the switchboard operators control the flow of electricity from a central point, whereas, auxiliary equipment operation work throughout the

Functions of SCADA (Supervisory Control and Data Acquisition) The supervisory control and data acquisition systems allow a few operators to monitor the generator. The following are the functions of SCADA. 1. Data Acquisition : It provides telemetered measurements and status information to operator. 2. Information display (limit violations, unplanned events). 3. Supervisory control (CBs (Circuit

Laser Beam Welding Characteristics The laser beam welding characteristics of the laser and electron beam are similar. The concentration of energy by both beams is similar with the laser having a power density in the order of 10°W/cm². The power density of the electron beam is only slightly greater. It is compared to a current

Friction Stir Welding (FSW) Friction Stir Welding (FSW) is a solid state welding process in which a rotating tool is fed along the joint line between two workpieces. It is used to join two facing surfaces. During welding, heat is generated due to friction and the metal is mechanically stirring to from the weld seam.

Hall effect sensor work is a type of magnetic sensor. A Hall effect sensor is a transducer that varies its output voltage in response to changes in magnetic field. In 1879 Edwin Hall discovered that: ‘when a conductor or semiconductor with current flowing in one direction was introduced perpendicular to a magnetic field a voltage

Point to Point Links The simplest transmission link is a point to point links line that has a transmitter on one end and a receiver on the order. This type of link places the least demand on optical fiber technology and thus sets the basis for examining more complex system architectures1-10. The design of an
