What is Power System Protection?
Power system protection is a collection of techniques, equipment, and practices used to identify and isolate electrical defects in a power system.
It is intended to protect the equipment, infrastructure, and users against harm caused by abnormal operating situations such as
- Short circuits,
- Overloads,
- Voltage fluctuations, and
- Other failures.
Protection systems often include
- Relays ,
- Circuit breakers ,
- Fuses , and
- Other devices
to immediately recognize problems and isolate the afflicted area of the system, preventing widespread outages or damage.
