Electrical Power Concepts
Power generated at the generating stations is transmitted to the end user through transmission and distribution lines. HVDC line refers high voltage direct current transmission whereas HVAC transfer high voltage AC power. The main objective during the power transmission is to reduce power losses. The big advantage of using HVAC system is that voltage can be … Read more
When conductor carries alternating current, it constantly produces alternating magnetic flux around it. This alternating magnetic flux induces circulating currents in the adjacent conductors. In simple words, when two or more conductors are placed close to each other, alternating flux in each conductor is produced by the nearby current carrying conductor. Induce eddy currents↗ increases … Read more
Overhead power lines are used to transmit and distribute electric power. The successful operation of overhead transmission lines depends on the mechanical design of lines. The main components of overhead transmission line are towers, conductors, earth wire, stock Bridge damper, jumper wire, spacer, Aerial Marker Balls, span and sag. Let discuss these components of overhead … Read more
Power generated at the generating stations is transmitted and distributed over long distance by using overhead line conductors. Overhead line conductors are supported on the poles and towers in such a way that the current from the conductor doesn’t flow to the earth through metallic tower structure. In simple words, line conductors must be insulated … Read more
