Earthing and grounding seem to be equivalent. However, there are some major differences. One example: earthing is focusing on safety whilst grounding is related to functionality and reliability. If the latter is not well respected and applied, winding degradation and bearing damage are common failure modes through shaft currents.

We inspect, detect and confirm the presence of leaking currents and advise on the most effective and proactive corrections to be made. 

Little hint: it is usually related to the grounding topology!
