Why are need earthing evar stracture in switchyard

Question

Accepted Answer

Earthing is necessary in switchyards to protect equipment and personnel from electrical hazards.

Earthing provides a low resistance path for fault currents to flow, preventing damage to equipment and reducing the risk of electrical shock to personnel.
It helps to maintain the potential of the equipment at zero volts, preventing the buildup of static electricity.
Earthing also helps to reduce electromagnetic interference (EMI) and radio frequency interference (RFI) in the switchyard.
Examples of earthing systems include rod earthing, strip earthing, and plate earthing.
Regular maintenance and testing of earthing systems is important to ensure their effectiveness.
