2. Electrical switchgear regulates, protects, and
isolates a power system with a variety of
controls housed in a metal enclosure.
3. High voltage switchgear
Low voltage switchgear
Medium voltage switchgear
4. The automated protective switchgear
primarily includes the circuit breaker and
relay.
The relay comes into action when a fault
occurs, and it usually closes the trip circuit
which automatically disconnects the faulty
line.
After that, the operative and healthy section
runs the normal and required supply load.
And therefore, there’s no damage to
apparatus and no disruption of supply.
5. While the occurrence of any fault or defect in
the power system, all electric apparatuses are
vulnerable to have a heavy current which
means the apparatus could get damaged and
the supply also gets disrupted.
