General Description

ADR219C is second generation Numerical Integrated Feeder Protection Relay for Traction Application.

  • Disturbance Recorder. 50 cycles of actual waveform of currents (45 pre-fault & 5 post fault) are captured & saved in the built-in memory with date time stamping, for analyzing fault.
  • Separate Communication Ports for SCADA (RS485) as well as Local testing (RS232C)
  • Fully communicable with IEC standard open protocol.
  • Very low burden on CT (less than 0.2VA) and PT (less than 0.2 VA).
  • Online display of R, X, V, I CB status and other digital and logical status.
  • Continuous monitoring of module’s internal hardware and alarm generation in case of failure of any critical components.
  • Large 20x4 LCD display for Parameter and setting display.
  • Facility to synchronised Relay time with external GPS network.
  • 10 Digital Output contacts for local alarm as well as tele-signalling.
  • 9 Optically isolated digital status input for monitoring of status and avoid used of external relay logic.
  • 100 nos of event memory, event such CB close, Trip, digital status change, relay pkp etc. All events are with date and time stamped up to 1ms.
