What is electrical zonal protection?

Electrical zonal protection is a technique used in power systems to enhance the reliability and safety of electrical networks. It involves dividing the electrical system into distinct zones, each monitored by protective devices that can detect faults or abnormalities within their designated zone. This approach allows for rapid isolation of faults, minimizing the impact on the overall system and ensuring that only the affected area is disconnected. By improving the speed and accuracy of fault detection, zonal protection helps maintain operational continuity and reduces the risk of widespread outages.
