GE Multilin C70 – Capacitor Bank Protection & Control System

$1.00

The C70 is an integrated protection, control, and monitoring device for shunt capacitor banks based on the well established and proven UR relay platform of GE Multilin. The C70 provides both the bank and system protection schemes for shunt capacitor bank protection. The current and voltage-based protection functions provide sensitive protection for grounded, ungrounded single, and parallel capacitor banks and banks with taps.

  • Protect capacitor banks for a variety of configurations with sensitive current and voltage balance protection functions
  • Advanced IEC 61850 Ed. 1 and Ed. 2 certified implementation, complete settings via SCL files and flexible process bus support (IEC 61850-9-2LE or IEC 61850-9-2 Hardfiber) ensures interoperability, device managing optimization and reduced cost of ownership
  • Routable GOOSE (R-GOOSE) enables GOOSE messages going beyond the substation, which enables wide area protection and control applications
  • Robust network security enabling Critical Infrastructure Protection through user command logging, and dual permission access control
  • Custom programmable logic for advanced shunt capacitor bank controls
  • Reduced relay-to-relay wiring and associated installation costs through high-speed inter-relay communications
  • Supports latest edition of waveform capture (COMTRADE 2013) simplifying fault records management
  • Application flexibility with multiple I/O options including high density I/O, programmable logic, modularity, and specific customization
  • An integrated large, full color display, provides real-time visualization and control of the protected bay, via a bay mimic as well as annunciator functionality and graphical visualization of phasors
