Earthing, Bonding, Lightning and Surge Protection

Earthing is the system that does nothing visible until a fault or a strike, and then determines whether anybody is hurt and whether the electronics survive. This course covers designing it. Delegates work through earthing system types and the fault current path, earth electrode design and soil resistivity measurement, step and touch potential calculation, and the bonding that keeps equipment at the same potential during an event. Lightning protection covers risk assessment, air termination and down conductor design. Surge protection is covered as a coordinated set of devices across the installation rather than a single unit, and the course closes on testing, measurement and the periodic verification an earthing system needs.

5 day course
