Protecting and controlling an evolving grid
The main purpose of a protection and control relay is to recognize any abnormal power system condition(s), or abnormally operating system component(s). Grid anomalies can be caused by over currents - the overload through lightning or malfunctioning electric equipment or a short circuit in the system. Based on the information gathered, the protection and control relay will initiate corrective actions that return the power distribution system to its normal operating state providing a safe environment for personnel and equipment. Selecting the right protection and control functions and methods, that meet local legislation, safety requirements and engineering practice, improves the performance and the reliability of the power protection system, thus minimizing the effects of network faults and preventing the disturbance from spreading to healthy parts of the network.
ABB’s Relion family of protection and control relays for secondary 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 secondary distribution. All ABB Relion protection and control relays leverage the same configuration software.
ABB supports customers and partners in staying ahead of increasing electrification needs, technology, and regulatory changes, providing the power to adapt to a rapidly evolving energy landscape.
ABB’s protection and control relays are available for original equipment manufacturers (OEM), panel builders and Engineering, Procurement and Construction (EPCs) partners to incorporate in their own installations or for use in new, retrofit or upgrade projects.
