1. SUBSTATION EQUIPMENT AND THEIR FUNCTIONS Substations INTRODUCTION: In Power System network‚ in order to transmit and distribute the generated power‚ it is necessary to install “SUBSTATIONS” at strategic points to work at required voltage level since “HIGH VOLTAGE TRANSMISSION” is resorted to. The Sub stations are classified as “GRID” of “RADIAL” Substations. The Grid station is installed in Grid network to reduce the voltage level from 230KV to 110 KV. The radial Station within Distribution net

“Solar Radiation and its Effects on Planet Earth” The Sun emits a tremendous amount of energy‚ in the form of electromagnetic radiation‚ into space. If we could somehow build a gigantic ball around the Sun that completely enclosed it‚ and lined that ball with perfectly efficient photovoltaic solar panels‚ we could capture all of that energy and convert it to electricity and be set in terms of Earth ’s energy needs for a very long time. Lacking such a fanciful sphere‚ most of the Sun ’s energy
