Electrical Power Systems for Non-Engineers




Introduction:

This course is dedicated to non-engineers to understand the basics and operations of electrical power systems. Commencing with the conventional method of generation of electricity to the fundamentals of renewable energy electrical power generation. In the transmission and distribution of electrical power the functions of power transformers, circuit breakers, electric motors, and earthing systems. Safety and hazards of electricity are the focal points in all electrical installations.

Basic single line diagram interpretation is essential for the understanding of the electrical installation power flow. The emphasis of alternating current (AC) systems will encompass the basic electrical units like voltage, current, power, power factor a frequency of a single-phase and three-phase systems. Maintenance culture complimented by standard testing and measuring instruments is essential to ensure the reliability and security of an electrical power system
