Electrical Substations and Switchyard DesignLiving Online
Electrical substations form important nodal points in all power networks. Substations can be of various capacities, voltages, configurations and types depending on what is the application for which the substation is being designed. Location and layout of a substation present a number of challenges to the designer due to a large variety of options available to a designer. There are ever so many constraints too that need to be kept in mind; technical, environmental and naturally financial. Arriving at an optimum design within these constraints is as much an art as it is a science. Designing a substation which will operate with utmost reliability for at the least three or four decades involves a thorough knowledge of the current state-of-the art equipment, emerging technologies, the tools for presenting and evaluating all available options and a good appreciation of power system operation and maintenance. This course will present a comprehensive capsule of all the knowledge essential for a substation designer and walk the participants through the substation design process using a set of interlinked case studies.
WHO SHOULD ATTEND?
This course is aimed at engineers who are already working as electrical system designers as well as those who belong to any of the fields listed below and wish to prepare themselves for moving into the role of a substation designer.
Utility engineers dealing with power transmission and distribution systems
Electrical engineers involved in power generating plants with utility scale generators
Electrical engineers in large industries who are associated with power distribution
Consulting engineers involved in design of substations

ENERGY-MANAGEMENT IN SMALL SCALE INDUSTRIES: A VITAL TOOL FOR SUSTAINABLE DEV...IAEME Publication
Risk of continuous depletion of natural resources of energy has led to a greater awareness for energy management throughout the world. Energy should not only be used wisely and economically, it should also be conserved effectively for future generations. Industry, being one of the major users of energy, by adopting energy conservation, can contribute substantially for social and economic development of a
country.
