Difference between Global Earthing and Integrated Earthing

Integrated grounding is a method of connecting all electrical systems (power, communication, control, lightning, etc.) in a building to a single grounding network. This minimizes potential differences (voltage differences), reduces interference between equipment, and lowers the risk of electric shock. It is similar to the concept of integrating all drainage pipes in a building into a single drainage system.

Global grounding is a method of configuring the entire building or industrial complex as a single grounding network beyond individual equipment units . In other words, the key is to design so that no potential difference occurs anywhere within a specific area. In order to apply global grounding, the internal grounding structure must be close to the integrated grounding to maintain a stable potential balance.

Integrated grounding is tying together the grounding system within a building into one , while global grounding is configuring a wider area (the entire building or region) as one grounding network.
