VAMP 259 Line manager for distance and line differential protection

The VAMP 259 line manager is used for applications where combined protection, remote and local control, measurement, power quality, alarming and status indication functions are needed. The manager is suitable for full-scheme distance protection and it incorporates line differental functions usually required for the protection of subtransmission cables and overhead lines.

Main Characteristics

• Distance protection including full scheme distance protection for 5 zones, 30 independent distance elements and  6 loops (21/21E).
  

• Pilot channel communication functionality for various protection schemes (85)
  

• Complete set of time- and instantaneous- overcurrent, overvoltage, undervoltage, and frequency protection functions
  

• Sensitive earth fault protection functions which are suitable for compensated, isolated and solidly grounded networks
  

• Programmable protection stages
  

• Auto-recloser function
  

• Synchrocheck function
  

• Switch-onto-fault(SOTF) functionality
  

• Digital input support for Trip Circuit Supervision
  

• Frequency stage df/dt (ROCOF)
  

• Fault value, alarm led display, event buffer, blackout data and disturbance recording storage in non volatile memory
  

• Inbuilt Ethernet interface
  

• Native solution for IEC61850 communication with support for GOOSE messages
  

• Removable / interchangeable communication modules for connecting the relay to various system communication solutions and medias

	Fortum Distribution of Karlstad, Sweden, has placed orders for six Vamp 259 line managers for installation at several subtransmission substations. The first delivery was a pilot installation commissioned in the spring of 2008 at the 40 kV Hova substation in the Västra Götaland region. >> Read more about the VAMP 259 reference
