Enhancing Reliability and Safety in Medium and High Voltage Networks with Ground Fault Protection Systems
Power distribution networks operate at medium and high voltage levels to efficiently deliver electricity from generation facilities to consumers. Ground faults, where current diverts from its intended path and leaks to earth (ground), pose a significant challenge in these networks. Ground Fault Protection (GFP) systems play a critical role in safeguarding medium and high voltage power distribution systems. They contribute to enhanced grid reliability by minimizing fault damage, isolating faults, and ensuring faster fault clearing times. This article explores the application of GFP systems in medium and high voltage power distribution networks and their benefits for system reliability and safety.
