Earthing
Types of Grounding: Industrial, Building, and Transformer Grounding
Grounding systems form the cornerstone of electrical safety and, when correctly implemented, prevent serious accidents.
Sector Solutions · 02
Energy and Electrical Infrastructure
Earthing networks and permanent joints that limit step and touch voltages in power plants, substations and switchyards.
The protection need
In power generation and transmission facilities the earthing system is at the centre of the design, both to distribute fault currents safely and to protect people from step and touch voltages. High fault currents require the joints to remain low-resistance for many years.
Principal risks and design criteria
- 01
High fault currents
Thermal and mechanical withstand of the earthing network and its joints.
- 02
Step and touch voltages
Mesh geometry determined by calculation, for the safety of people on site.
- 03
Open switchyards
Direct lightning protection with mast-type and catenary air-termination systems.
- 04
Control buildings
The need for surge protection and equipotential bonding in protection and control systems.
