Product Overview

• Part No: P40 AGILE MICOM P141
• Brand: ALSTOM / GE Vernova

• Category: Numerical Feeder Management Protection RelayMiCOM P40 Agile P141 is a full‑featured numerical feeder protection relay under MiCOM P40 Agile protection platform. It integrates protection, measurement, control, fault recording and communication functions, developed for overhead lines and underground cable feeders of distribution and transmission substations. The unit supports complete overcurrent, earth‑fault and voltage protection logics, as well as auto‑reclose, breaker control and programmable scheme logic. It is fitted with local LCD HMI and multi‑color programmable LED indicators for onsite parameter configuration, status check and fault event review. Multiple standard industrial communication protocols are available for connection with SCADA and substation automation systems. It is widely used in power utilities, thermal power plants and industrial self‑power plants, acting as original replacement spare for old substation protection devices.
