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...
3Φ AC synchronous motor Revolving armature type Revolving field type Conventional 3Φ Synchronous Motor : (Revolving Field Type) Stator : Stator is made up of silicon steel stampings. Stator slots carry a balanced 3Φ armature...
Merits of SRM Construction is simple and robust. Rotor carries no windings, no sliprings, no brushes, less maintenance. There is no permanent magnets. Ventilating system is simpler as losses takes place mostly in the...
SRM is a single excited and double salient pole electric motor. It is an electromagnetic and electrodynamic equipment. Switched reluctance motor operating principle is similar to a single-stack variable-reluctance stepping motor...
Figure shows evolution of brushless dc motor. Conventional DC Motor The first stage of evolution of DC motor is conventional type DC motor. It is an electro magnetic and electro dynamic equipment. Sator Stator is made up of...
