A hallmark of their service is selective coordination. By calculating fault currents and setting protective relays with precision, Ashfaq Hussain’s solutions ensure that when a disturbance occurs, only the affected section of the grid is isolated—keeping the rest of the system operational. This minimizes downtime and saves millions in lost revenue.
Since November 1996, Ashfaq Hussain has been serving as a lecturer at the . Here, he teaches theory and lab courses in Electrical Engineering Technology and coordinates the Electrical Power Engineering Technology Program. His academic credentials are equally impressive, holding a Master of Science in Electrical Engineering from Oklahoma State University, USA (1990), and a Bachelor of Science in Electrical Engineering from the University of Engineering and Technology, Lahore, Pakistan (1986).
In the realm of electrical engineering education, particularly in the Indian subcontinent, the name is almost synonymous with Power System Analysis . While he may not be a corporate CEO or a grid manager, his contributions as an author and academic have provided foundational solutions to countless engineering students and professionals grappling with the complexities of modern power systems. His work, primarily the textbook Power System Analysis (often published by Dhanpat Rai & Co.), serves as a bridge between theoretical electromagnetism and real-world grid challenges. This essay explores how Hussain’s structured approach—spanning load flow, fault analysis, and stability—offers comprehensive solutions to perennial power system problems.
