P54b Multi-ended Line Differential Protection Systems

We are the supplier and trader of the P54B Multi-ended Line Differential Protection Systems. It is suitable for direct fibre and multiplexed (IEEE C37.94) networks, including MPLS systems. The ability to locally take any end off-line for maintenance. The full suite of monitoring, control and recording capabilities plus fault locator, auto reclose and check synchronism





Its Specifications are:
Subcycle tripping time up to 4-ended topology (<1.25 cycle for 5 or 6 ends)
Highly selective and sensitive unit protection, with capacitive current compensation for long lines or cables
Full support of SONET/SDH channel switching 8 teleprotection logic bits from and to each end via MODEM, fibre, or MUX channel
Compatibility with modern Ethernet communications equipment
New CT saturation technique reduces CT dimensioning requirements and saves on scheme cost
Advanced IEC61850 Edition 2 implementation with complete settings via SCL files
Redundant communications with zero downtime using optional PRP/HSR protocols
Wide range of supported protocols Courier/K-Bus, IEC 60870-5-103, DNP 3.0 (EAI-485 or Ethernet) and IEC 61850 Edition 2
Harsh environment coating as standard to all MiCOM relays to protect against corrosive gases such as H2S or SO2

Its Application are:
Adapted to suit many different substation and protected feeder topologies:
Current differential protection for up to 6 line or cable ends, maximizing connection of renewable generation, reducing greenhouse gas emissions
Highly selective and sensitive unit protection, with capacitive current compensation for long lines or cables
Ability to locally take any end off-line for maintenance
Transmission and sub transmission: P54C and P54E use the same hardware as well-proven MiCOM Agile P543 and P545 models, offering scalability for large numbers of binary inputs/outputs
Distribution: P54A and P54B offer compact feeder differential in a 40TE half-rack case
