Breaker Management SIPROTEC 7VK87

The SIPROTEC 7VK87 circuit-breaker management device is specifically designed to manage circuit-breakers reliably.

Its modular structure and flexibility, coupled with the high-performing DIGSI 5 engineering tool, allows the SIPROTEC 5 7VK87 to offer future-oriented system solutions for protection, control, automation, monitoring, and Power Quality (PQ) basic.

Basic Features

  • Automatic reclosing function, synchrocheck, circuit-breaker failure protection
  • Tripping: 1-pole and 3-pole or 3-pole
  • 1-pole automatic reclosing function with detection secondary arc
  • Circuit-breaker failure protection for 1-pole and 3-pole tripping
  • Point-on-wave switching
  • Control, synchrocheck and switchgear interlocking protection
  • Arc and voltage protection
  • Up to 4 pluggable communication modules, usable for different and redundant protocols (IEC 61850-8-1, IEC 61850-9-2 Client, IEC 60870-5-103, IEC 60870-5-104, Modbus TCP, DNP3 serial and TCP, PROFINET I/O, and PROFINET I/O S2 redundancy)
  • Reliable data transmission via PRP and HSR redundancy protocols
  • Extensive cybersecurity functionality (e.g. role-based access control (RBAC), protocolling security-related events, signed firmware or authenticated network access IEEE 802.1X)
  • Provides simple, quick and secure access to the device via a standard Web browser to display all information and diagnostic data, as well as vector diagrams, single-line diagrams, and device display pages
  • Phasor Measurement Unit (PMU) for synchrophasor measured values and IEEE C37.118 protocol
  • Time synchronization using IEEE 1588
  • Enables powerful fault recording (buffer for a max. record time of 80 sec. at 8 kHz or 320 sec. at 2 kHz)
  • Flexible adjustment of I/O quantity structure within the scope of the SIPROTEC 5 modular system
