The design and effective performance of an earthing solution can have a major impact on potential safety, security of electricity supplies, power quality and construction costs.

Earthing system design has become more complex in recent years due to higher fault currents, limited substation areas, use of PVC insulated distribution cables, proximity of homes and third party equipment such as telecommunications. The standards concerning Earthing have also further developed, introducing new concepts, design criteria and limit values.
