VAMP 265 Generator, transformer and motor diferential protection relay

 
   

The protection functions, many communication protocols and numerous auxiliary functions make the VAMP 265 perfect for utility and industrial power generation applications.

The VAMP 265 relay is, together with the generator protection relay VAMP 210, used for protection of the generator. The overcurrent and earth-fault protection functions are used as back-up protection.
 

Differential protection features

  • Dual slope bias characteristics

  • Selectable second harmonic blocking

  • Fast operating time

  • High stability during through faults

Protection

  • Two differential overcurrent stages

  • Overcurrent stage

  • Earth-fault overcurrent stage

  • Circuit Breaker Failure protection

  • Arc flash protection (option)


Key Features:
  • Complete differential protection for generators, transformers and motors
  • Use together with VAMP 210 for a complete generation protection scheme
  • High stability against through faults
  • 2nd and 5th harmonic blocking
  • Inbuilt Ethernet interface with Native IEC61850 communication including GOOSE messages
  • Numerical CT ratio correction
  • Selectable connection groups
  • Event handling and fault registration, up to 2000 event records
  • Disturbance recorder
  • Dual slope bias characteristic with fast operating time
  • High stability during through faults
  • Two differential overcurrent stages: Overcurrent stage and Earth fault overcurrent stage
  • CB Failure protection
  • Optional arc protection
  • Standard VAMP communication modules for connecting the relay to various system communication solutions and medias (order options)
