Relay Protection of the Brazilian Power Supply Bureau
The Brazilian standards for relay protection provide guidelines for the design, installation, testing, and maintenance of protective relays in power systems. They encompass a wide range of protection schemes, including overcurrent, distance, differential, and transformer. Relay protection is a critical aspect of electrical power systems that ensures the safe and reliable operation of transmission and distribution networks. To ensure uniformity and compliance with recognized best practices, various countries have their own set of standards for relay protection. For example, unselective protection operation during a medium voltage network fault will cause an outage for an unnecessarily large number of consumers. While this is bad, It's not a.
