What does "electrical isolation" refer to in grid safety?

Electrical isolation refers to the act of disconnecting specific sections of the electrical grid to perform maintenance or repairs safely. This process is crucial for ensuring that workers can operate without the risk of electrical shock or other hazards that could arise from live wires or operational equipment. By isolating the area where maintenance is needed, it prevents the flow of electricity in that part of the grid, allowing for a safe working environment.

In the context of grid safety, this practice helps to minimize risks and contributes to the overall reliability of the electrical system. It ensures that when maintenance or inspections are conducted, they can be done without jeopardizing the safety of personnel or the integrity of the entire grid. This understanding is central to maintaining a safe and efficient electrical infrastructure.
