Course Introduction

Grounding systems are vital to the integrity of power systems, ensuring safety and reliability. They offer a shared reference for live electrical conductors, allowing surge currents to safely dissipate into the soil and thereby safeguarding personnel and the public. The proper design and application of grounding techniques is crucial for controlling electrical noise and mitigating potential issues within power systems and their associated controls and communications.

 

This Grounding, Bonding and Lightning Protection of Electrical Systems course is essential for engineers and technicians involved in power supply systems. It delves into grounding system design principles, highlighting the significant role they play in operational safety and the prevention of costly errors due to system failures or extended downtime.

 

Course Focus: this course is built around foundational grounding concepts, common power system failures, and damage prevention strategies related to grounding system efficiency and protection device selection. Delegates work with real-world examples and case studies throughout, and content is aligned to internationally recognised references including IEEE Std 80 (substation grounding), IEC 62305 (lightning protection), and the South African national standard SANS 10313.
