Provides test procedures based on the fall of potential method and actual touch and step voltage measurements for the purpose of validating a safe earthing design. Includes procedures for both large or small earthing systems, safety requirements (for undertaking the tests) and recommended testing equipment.

Key earthing design concepts covered including Grid Potential Rise, design to reduce touch and step voltages, fault current distribution, effects of soil resistivity and use of rods to improve safety along with calculation and modelling examples.
