In this session, we dive deep into the critical process of Earthing Conductor Sizing, a fundamental aspect of Power System safety and protection. Proper sizing ensures that the ground system can withstand high fault currents without melting or causing system failure.
What you will learn: The Core Formula: Understanding the adiabatic equation , where $S$ is the cross-sectional area, $I$ is the fault current, $t$ is the clearing time, and $k$ is the material constant.Material Selection: Comparison between Copper, Aluminum, and Galvanized Iron (GI) based on their constant ($k$) values.Safety Factors: Why a 1.5x factor is often applied in practical engineering to account for corrosion and joints. Step-by-Step Example: A real-world calculation for a 20kA fault current with a 0.5s clearing time.Taheruzzaman's Insights: Key considerations from the renowned academic approach used in BSc Engineering curricula for determining optimal conductor thickness.This guide is essential for Electrical Engineering students (BSc/MSc), practicing design engineers, and those preparing for technical interviews in the power sector.
