Protective Relays: Function, Features & Operation
Learn more about the work of protective relays in power systems, their features and operating principle.
Home / Power Components Relay Protection
It covers the protection methods for generators, transformers, buses, and transmission lines using various relay types to detect and isolate faults efficiently. Protective relays and devices have been developed over 100 years ago to provide "last line" of defense for the electrical systems. They are intended to quickly identify a fault and isolate it so the balance of the system continue to run under normal conditions. ABB's Relion family of protection and control relays for primary distribution offers a wide range of products for protection, control, measurement and supervision of power distribution systems for IEC and ANSI applications – from generation and interconnected grids in primary distribution. The global energy transition is ushering in a new era of power electronic-dominated grids (PEDGs), to complement the increase in the widespread integration of renewable sources like wind and solar. It is reshaping traditional grid architecture and making way for more flexible, efficient and.
