New Age International (P) Ltd., Publishers A Complete Guide To Electrical Design by Brigadier Arvind Agrawal (Retired)
Electrical Power is generated by many methods which could be a hydro electric power station or a thermal power station or a nuclear power station or a diesel power station or many more methods. These power stations are generally far from the point of use of this power, the power is thus required to be transported from power stations to load centres. This is also called wheeling. To limit the losses in wheeling the power, a very high voltage is used. At the load centres, this high voltage is stepped down to useful voltage. It is generally done in multiple stages. Many types of sub–stations are used to step down the power which could be Gas Insulated or Air Insulated sub–station.
Having stepped down the electrical power to useful voltage, the power needs to be distributed economically. The useful content of the power (power factor) kVA should be upwards of 0.9. In case power factor is below 0.9, it needs to be corrected using capacitor banks.
Safety in electrical design is a very important factor. A poorly designed system may lead to fatal accidents. The system has to be designed with earthing and lightning protection system.
Internal power distribution is as important, since a right design will give long trouble–free service to the area served.
MEP is the heart of any project. Out of all services included in MEP, Electrical supply is the most important and constitutes the major part of MEP Design. This book covers the entire design process of electrical design at one place. It can be used as a textbook by undergraduate and postgraduate engineering students as well as practicing engineers and consultants. An effort has been made to provide all design related data and tables in this book. Many solved and unsolved examples have been added for practice.
