RC Phase Shift Oscillator Using Op amp: RC Phase Shift Oscillator basically consists of an amplifier and a feedback network consisting of resistors and capacitors arranged in ladder fashion. Hence…
Single Phase Synchronous Generator: Certain applications, usually restricted to less than 10 kVA are better served by a Single Phase Synchronous Generator. Examples are emergency, domestic/office supply, portable power for…
Phase Conversion in Transformer: Three Phase to Two Phase Conversion Transformer (Scott-T transformer or Scott Connection): Phase conversion from three to two phase is needed in special cases, such as…
Three Winding Transformer: Three Winding Transformer may be built with a third winding, called the tertiary, in addition to the primary and secondary. Various purposes which dictate the use of…
Three phase Transformer Bank of Single phase Transformers: The different Three phase Transformer Bank of Single phase Transformers are namely, Delta/delta connection: The supply voltage provides only sinusoidal magnetizing current…
Three Phase Transformer Connections: In generation, transformation, transmission and utilization of electric energy it can be shown that it is economical to use the three-phase system rather than the single-phase.…
Different Groups of Systems of Electric Traction: As already mentioned, systems of electric traction may be divided into two main groups. (1) The group consisting of vehicles which receive electric…
Diesel Electric Traction System: Because of high initial cost, electric traction is justified only where there is sufficient volume of traffic. Diesel Electric Traction System is preferable where the traffic…
