DC Distribution System: It is a common knowledge that electric power is almost exclusively generated, transmitted and disÂtributed as a.c. However, for certain applications, d.c. supply is absolutely necessary. For…
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…
Constants of a Transmission Line: A transmission line has resistance, inductance and capacitance uniformly distributed along the whole length of the line. Before we pass on to the methods of…
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,…
Various Types of Electricity Tariff: The electrical energy produced by a power station is delivered to a large number of consumers. The consumers can be persuaded to use electrical energy…
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…
