What you will learn
At the end of this unit, you will:

• Appreciate how atmospheric lightning uses the earth as an energy dissipation path.
• Appreciate the hazardous outcomes of lightning discharges in the ground.
• Appreciate the important role of soil electrical resistivity for step and touch potential considerations.
• Appreciate the requirements of BS EN 62305 for good earthing.
Who should learn
Before embarking on the course, it was expected that the delegate/student would have learned the use of Ohm’s Law, concept of resistance, inductance and capacitance. Ideally, the delegate/student is working in the field of electrical services engineering either in design/inspection or in installation/testing.
