Agile Protection Relays

Alstom’s Agile range protects critical power system assets, right from industrial systems, through distribution, rail, generation and up to the highest transmission voltages.  Short-circuits, overloads and other faults are cleared in tripping times as fast as sub-cycle. 

From the simplest self-powered P50 Agile relay, through the colour touch-screen P60 Agile, up to the compact and modular MiCOM P40 Agile ranges, security and dependability of operation is paramount.  Agile devices are multifunction and fully numerical, including cybersecure substation communications interoperable with international standards such as IEC 61850 edition 2.  Applications include feeder, motor, generator, distance, differential, transformer, line, busbar, voltage and frequency intelligent solutions.

With this full portfolio of protection relays, we have the devices, schemes and expertise to protect your power network.
