Switchgear functioned mainly as protection, which including:
Overcurrent Protection: Prevents damage from excessive current.
Short Circuit Protection: Quickly interrupts fault currents.
Ground Fault Protection: Detects and isolates ground faults to prevent shocks and equipment damage.
Overvoltage Protection: Protects against voltage surges.
Arc Flash Protection: Switchgear is designed with features like arc chutes, blast-resistant doors, and arc-resistant coatings to contain and mitigate the effects of arc flash incidents, which are explosive discharges of energy due to an electrical fault.
