P40 Agile Feeder Management

The P14N non-directional feeder, P14D directional feeder and P94V voltage and frequency IEDs bring the design rigor and technology of transmission applications to the entire utility and industrial market. The footprints of both the device physical size and the lifecycle environmental impact have been minimized using state-of-the-art design, component, and process selection. Agile solutions from GE are ideal for new-build and retrofit alike.

Agility and Versatility

MiCOM P40 Agile IEDs provide an integrated solution for the complete protection, control and monitoring of electrical power systems. Application for overhead lines, underground cables, busbars, breakers, transformers, reactors and distributed generation is supported, right from distribution (as primary protection) to transmission voltage levels (as back-up). The IEDs are suitable for a wide variety of applications in solidly-earthed, resistance-earthed and Petersen coil systems.
