Learning Objectives

Upon successful completion of this course, participants will be able to:

1. Fundamentals of Electrical Load Estimation

• Understand the importance of load estimation in electrical system design.
• Identify types of electrical loads:
• Resistive loads (heating, lighting).
• Inductive loads (motors, transformers, HVAC).
• Capacitive loads (power factor correction capacitors).
• Differentiate between continuous, intermittent, and peak loads.

2. Load Classification and Demand Analysis

• Categorize loads based on application (lighting, HVAC, motors, IT equipment, etc.).
• Define and apply:
• Connected load vs. operating load.
• Demand factor and diversity factor in system design.
• Load factor and utilization factor for energy efficiency.

3. Methods for Electrical Load Estimation
