Numerical Integrated Digital Traction Protection Relay :ADR219AGeneral DescriptionADR219A is second generation Numerical Integrated Feeder Relay for Traction Protection Application. It consist all the necessary protection and monitoring functions required for traction feeder.In-built CB Trip Circuit monitoring during close as well as open condition Separate Communication Ports for SCADA (RS485) as well as Local testing (RS232C) 100 nos of event memory, event such CB close, Trip, status change, relay pkp etc. Breaker Failure Detection.(BF) Auto Reclose Relay (ARR).(79) IEC standard open protocol. Continuous monitoring of module’s internal hardware and alarm generation in case of failure of any critical components. Large 20x4 LCD display. Facility to synchronised Relay time through SCADA through communications. or GPS 13 Digital Output contacts for local alarm Tele-signalling & Control 6 Digital Output (DO) and 8 Optically isolated digital status input (DI) All events are with date and time stamped up to 1ms. 9 Optically isolated digital status input for monitoring of status and avoid auxiliary relays.Specially designed for Traction OHE protection. As per RDSO specs TI/SP/PSI/PROTCT/5070. Digital Distance Instantaneous Over-Current Protection. PT Fuse Monitoring. Disturbance Recorder. 50 cycles of actual waveform of voltage & current are captured & saved in the built-in memory with date time stamping, for analyzing fault condition & fault location.
