Feature

  • Integrated protection, measurement and control functions.
  • Supporting IEC61850, Modbus, and IEC 60870-5-103.
  • Customizing protection functions by logical equations, such as Standby Automatic Switching and VQC.
  • Networked protection through IEC 61850 GOOSE and logical equations.
  • Real-time dynamic display of the action of each protection function, and the action process is visible.
  • Recording the complete information during the action process.
  • Recording large volume disturbance data and turning it into standard COMTRADE format.
  • The transformer protection relay can be maintained through the front panel maintenance port (TYPE-C USB) and the Ethernet port on the back of the device.
