GE C70 | Capacitor Bank Protection and Control System
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.


  • Protection, control, monitoring and automation of shunt capacitor banks at different voltage levels
  • Suitable for protecting multiple capacitor banks
  • Sensitive protection for grounded and ungrounded single and parallel capacitor banks and banks with taps, for a variety of capacitor bank configurations
  • Capacitor bank-based automatic voltage regulator (AVR) and capacitor control supervision

Key Benefits

  • Protect capacitor banks in a variety of configurations with sensitive current and voltage balance protection functions
  • Adaptive compensation techniques truly compensate for the inherent bank unbalance, providing sensitive protection
  • Custom programmable logics for advanced shunt capacitor bank controls
  • Flexible automatic voltage regulation of shunt capacitor banks along with control supervision
  • Three independent fiber or copper Ethernet ports for simultaneous/ dedicated network connections with 1 microsecond time synchronization via LAN with IEEE® 1588 support
  • Reduced relay-to-relay wiring and associated installation costs through high-speed inter-relay communications
  • Embedded IEC 61850® protocol
  • Increase network availability by reducing failover time to zero through IEC 62439-3 "PRP" support
  • CyberSentry™ provides high-end cyber security aligned to industry standards and services (NERC® CIP, AAA, Radius, RBAC, Syslog)
  • Complete IEC® 61850 Process Bus solution provides resource optimization and minimizes total P&C life cycle costs
