Introduction

Modern industrial, commercial, infrastructure, and utility operations depend heavily on reliable and safe electrical power systems. Professionals from non-electrical engineering disciplines are increasingly required to interact with electrical equipment, participate in multidisciplinary projects, evaluate technical information, coordinate with electrical specialists, and contribute to operational and maintenance decisions. A practical understanding of electrical power systems is therefore essential even when electrical engineering is not their primary discipline.

This training program, designed by Global Horizon Training Center, provides participants with a structured and accessible introduction to the fundamentals of electrical power systems without requiring an electrical engineering background. The program explains electrical concepts using straightforward engineering terminology and emphasizes how electricity is generated, transmitted, distributed, controlled, protected, and ultimately utilized.

Throughout the five-day program, participants will develop an understanding of basic electrical quantities, AC and three-phase systems, generation and grid architecture, transformers, substations, switchgear, motors, protection, grounding, power quality, and electrical safety. Particular emphasis is placed on understanding system relationships and recognizing equipment functions rather than performing advanced electrical design calculations.

Objectives

By the end of this training program, participants will be able to:

• Explain the fundamental principles and terminology of electrical engineering.

• Understand voltage, current, resistance, power, energy, frequency, and power factor.

• Distinguish between AC and DC electrical systems.

• Understand the principles of single-phase and three-phase electrical systems.

• Describe the complete electrical power chain from generation through transmission and distribution to the end user.

• Identify the major equipment used in electrical power systems and explain its function.

• Understand the operating principles and applications of transformers.

• Recognize the functions of substations, switchgear, circuit breakers, isolators, and protection devices.

• Understand the basic operating principles of AC motors and generators.

• Read and interpret basic electrical single-line diagrams and equipment symbols.

• Understand the fundamentals of electrical faults and protection systems.

• Explain the purpose and importance of grounding and earthing systems.

• Recognize common power-quality problems and their operational consequences.

• Understand electrical hazards and fundamental electrical safety principles.

• Communicate more effectively with electrical engineers, contractors, operators, and maintenance personnel.

• Participate more confidently in multidisciplinary projects involving electrical systems.

Course Methodology

The program uses a structured, concept-based methodology specifically suited to professionals without a formal electrical engineering background.

Technical concepts are introduced progressively, beginning with basic electrical principles and advancing toward complete power-system architecture and equipment. Complex electrical concepts are translated into clear engineering language and supported by diagrams, simplified calculations, equipment illustrations, and industrial examples.

The methodology includes:

• Instructor-led technical presentations.

• Simplified explanations of electrical principles.

• Electrical system and equipment diagrams.

• Interpretation of single-line diagrams.

• Short calculation examples for key electrical quantities.

• Industrial and utility-based examples.

• Equipment identification exercises.

• Case-based discussions of electrical faults and operational issues.

• Safety scenarios and hazard-recognition discussions.

• Question-and-answer and knowledge-review sessions.

Organizational Impact

Organizations whose non-electrical personnel develop a stronger understanding of electrical power systems can benefit from improved interdisciplinary coordination, operational awareness, and technical decision-making.

The program will contribute to:

• Improved communication between electrical and non-electrical engineering disciplines.
