Protocol converters, GPS Synchronism and Pilot Wire Interfaces for MiCOM line differential relays. Models available: MiCOM P591, MiCOM P592, MiCOM P593, MiCOM P594, MiCOM P595
MiCOM P59x range features several products designed for substation integration. Initially designed for Current Differential schemes, these units have a high degree of accuracy and high speed operation. They are separated into 3 categories:
MiCOM P591 and MiCOM P593 Units are stand alone fiber optic to electrical communications interface units that allow the MiCOM P54x and MiCOM P52x Current Differential Relays to be connected to remote pulse code modulation (PCM) multiplexing equipment, using 64 kbit/sec data channels conforming to ITU-T recommendations G.703 or X.21.
MiCOM P595 is an EIA(RS)485 to pilot wire interface for relay connection to unconditioned twisted pair pilots. It provides secure communications on unconditioned twisted pair pilot wires for use with MiCOM P52x Current Differential Relays. The interfacing device accepts EIA(RS)485 from the P521 and uses an internal modem to drive a 4-wire signalling link, ensuring fast operation of the differential protection.
