Objectives of Earthing in Switchyards
- Safety of Personnel: Prevents electric shock hazards by maintaining ground potential and reducing touch and step voltages.
- Equipment Protection: Ensures the proper operation of protective devices and minimizes damage to equipment during fault conditions.
- System Reliability: Enhances the stability and reliability of the power system by providing a low-resistance path to earth.
- Lightning Protection: Safely dissipates lightning surges and protects the switchyard from lightning-induced overvoltages.
