Advanced Electrical Engineering

INTRODUCTION

Electrical Engineering is the comprehensive field that encompasses research, development, manufacturing, installation, operation, maintenance, and management of equipment, plant, and systems within the electrical, electronic, communication, and computer systems domains. These activities are vital across various sectors, including electricity generation, transmission, distribution, electrical installations, electrical equipment manufacturing, instrumentation, control systems, communication networks, electronic equipment, and computer system integration and control.

The Al-Majd Pathways Centre (APC) presents an interactive Electrical Engineering Advanced Workshop aimed at providing participants with an in-depth understanding of power stations, transmission & distribution systems, and zone substations, encompassing both primary and secondary systems. This training equips professionals with essential skills such as power system studies, transmission systems considerations, LV and MV distribution system design, substation equipment selection, power system protection & automation, and earthing system design. By applying these engineering skills to real-world challenges, participants will gain valuable insights and enhance their problem-solving capabilities.
