Mechanical Principles in Transmission Lines: Mechanical Principles in Transmission Lines design should depend to some extent on the importance of continuity of operation in the line under consideration. In general, the…
Sag in Overhead Transmission Lines: While erecting an Sag in Overhead Transmission Lines, it is very important that conductors are under safe tension. If the conductors are too much stretched…
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…
Introduction to Overhead Line: Electric power can be transmitted or distributed either by means of underground cables or by overhead line. The underground cables are rarely used for power transmission…
Control of DC Drives Using Microprocessors: The dc motors fed from thyristor converters for variable speeds are being exÂtensively used in general industrial applications. A dual converter, which is a…
Wound Rotor Induction Motor with Subsynchronous Converter Cascade in the Rotor Circuit: The following points favour the application of a slip ring motor having static slip energy recovery scheme in the…
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…
Machine Tools Motors Requirements: The Machine Tools Motors Requirements are: The motors must be reliable and low cost, requiring less maintenance. They must be capable of speed control. Some applications…
