What is the definition of 'Grounded' in electrical terms?

The term 'Grounded' in electrical terms refers to being connected to the earth or another conducting body. This connection serves as a safety measure, allowing excess electrical charge to be safely dissipated into the ground, which helps to prevent electric shocks, protects equipment, and stabilizes voltage levels within electrical systems. Grounding is fundamental in ensuring the safety of electrical installations and is a critical aspect of electrical engineering practices.

The other definitions do not accurately describe the grounding process in the context of electrical terminology. Being disconnected from any electrical source does not imply grounding; instead, it refers to an inactive state. Similarly, a connection to a generator or high-voltage line does not involve grounding; such connections may create unsafe conditions without a grounding path. Lastly, grounding only during maintenance work does not encapsulate the continuous safety role that grounding plays in an electrical system; grounding is typically a permanent feature in electrical installations to ensure ongoing safety under normal operating conditions.
