Schneider Electric MiCOM P138 Numerical Rail Catenary Protection Relay
Schneider Electric MiCOM P138 Numerical Rail Catenary Protection Relay is designed to provide directional overcurrent protection for railway power supply systems. It is used in conventional and autotransformer-fed (AT) railway networks where dependable protection of catenary feeders and traction power equipment is essential for maintaining reliable rail operations.
The MiCOM P138 combines protection, automation and communication functions in a single relay. It supports a wide range of railway protection applications and can be configured to match different operating conditions through four independent setting groups. This allows the relay to adapt to changing feeder arrangements and different network configurations without requiring major changes to the protection scheme.
The relay integrates easily with railway substations and catenary management systems through multiple communication interfaces. It also supports InterMiCOM teleprotection for fast relay-to-relay communication between line ends. Its modular construction and flexible mounting options make the MiCOM P138 suitable for both new railway projects and upgrades of existing protection systems.
