Here’s a brief overview of its main functions:

1. Control: Switchgear allows operators to control the flow of electricity within a system. For example, switches can be used to turn on or off specific parts of the system.
2. Protection: Circuit breakers and fuses protect the electrical system from damage caused by faults like short circuits or overloads. When a fault occurs, these devices interrupt the flow of electricity to prevent damage.
3. Isolation: Disconnectors and isolators provide a way to safely isolate parts of the system for maintenance or repair, ensuring that no current flows through those sections while work is being carried out.
4. Monitoring: Some switchgear systems come with monitoring capabilities to provide information about the operational status and health of the electrical system.

Switchgear can be found in various settings, including industrial plants, commercial buildings, and utility systems, and comes in different forms, such as air-insulated switchgear (AIS) or gas-insulated switchgear (GIS).
