Performance of Three Phase Short Transmission Line: For reasons associated with economy, transmission of electric power is done by Three Phase Short Transmission Line. This system may be regarded as…
Types of Insulators in Transmission Lines: The overhead line conductors should be supported on the poles or towers in such a way that currents from conductors do not flow to…
Line Support: The supporting structures for overhead line conductors are various types of poles and towers called line support. In general, the line supports should have the following properties :…
Comparison of AC Transmission and DC Transmission: The electric power can be transmitted either by means of d.c. or a.c. Each system has its own merits and demerits. It is,…
Power Factor Correction Circuit: To calculate Power Factor Correction Circuit, Consider an inductive load taking a lagging current I at a power factor cos Φ1. To develop Power Factor Improvement…
Low Power Factor: The Low Power Factor plays an importance role in ac. circuits since power consumed depends upon this factor. It is clear from above that for fixed power…
Power Factor: The electrical energy is almost exclusively generated, transmitted and distributed in the form of alternating current. Therefore, the question of power factor immediately comes into picture. Most of…
Centrifugal Pump Load: Centrifugal Pump Load are used as boiler feed pumps and for pumping water in water pipe lines. The former must be adapted to the variable output of…
