Batteries : The most traditional of all energy storage for power system is the electrochemical energy storage (EES). The major classification can be made in three categories. They are primary batteries, secondary batteries, and...
Solar electric or PV systems convert some of the energy in sunlight directly into electricity. PV cells are made primarily of silicon, the second most abundant element in the earth’s crust and the same semiconductor material...
The method known as SCADA has long been used to control transmission systems, providing the operational flexibility and speed required for efficient and reliable performance. The use of SCADA in the distribution system is...
After World War II, the drive to electrify the remaining rural and sparsely populated areas of the United States was renewed. Providing fully rated circuit breakers for switching loaded circuits was frequently beyond budget...
Sources : In circuit analysis, the goal is to start with a connected set of circuit elements such as resistors, capacitors, operational amplifiers, and other devices, and to find the voltages across and currents through each...
Definition of Electric Circuit : An electric circuit is a collection of electrical devices and components connected together for the purpose of processing information or energy in electrical form. An electric circuit may be...
GEO is also called as geosynchronous (or synchronous) orbits, which has 24 hour period of revolution but are inclined with respect to equator. Orbits that are below a mean altitude of about 36,000 km have periods of revolution...
The communication is established to the satellite through earth station. The earth station can be located on the ship at the sea, or it can be located on the space craft or actually on the earth. The location of the earth station...
We know that the satellite can receive and transmit one of the bands given in Table For each band, the uplink and downlink frequencies are separate. Frequency division multiplexing of the complete uplink and downlink range of...
