Handbooks
Substation engineers nowdays are involved in projects from design and conceptualization to maintenance. Because of the wide range of industries using electrical engineers, many engineers specialize in some of the sub-discipline of electrical engineering.
Depending on background and expertise, projects can include systems such as energy transmission and distribution, protection and control etc.

The basics of power system protection that every engineer should know about
Protection is the branch of electric power engineering concerned with the principles of design and operation of equipment (called ‘relays’ or ‘protective relays’) that detects abnormal power system conditions, and… Read more
Fault calculation methods for industrial and commercial power systems
There are two major problems that can occur in electrical systems: these are open circuits and short circuits. Of the two, the latter is the most dangerous because it can… Read more
Losses in the transmission and distribution networks and ways to reduce them
When current flows in a transmission line, the characteristics exhibited are explained in terms of magnetic and electric field interaction. The phenomena that results from field interactions is represented by… Read more
Practical guidelines to electrical installation design of residential buildings
When designing electricity supply to a residential building, design power for both separate groups of the switchgear and the feeding lead in general must be determined, considering the existing or… Read more
Design guidelines for substation and power distribution systems of buildings
This guide enables its readers to assess electrical load of a building and thus enabling to find out the required capacity of the switchgears, transformers etc. It deals with 33… Read more
Proper selection and overcurrent coordination of LV/MV protective devices
Selectivity between series protective devices is difficult to achieve unless the engineer responsible for specifying and purchasing the distribution equipment is familiar with available equipment features and functions. The engineer… Read more
