Vectorical Delta-I Type high resistive fault selective relay. :ADR219CGeneral DescriptionADR219C 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.Specially designed for Traction OHE Protection. As per RDSO specs TI/SP/PSI/PROTCT/4050. Operating / Non Operating Zone user defined by means of Reactance (X) Blinder. Independent contacts for Trip, Annunciation & Tele Intelligent contacts. Programmable Ä-I – 1.0 Amp to 6.0 Amp (with minimum Trip Time of 70ms). Programmable Additional Time Delay of 00ms to 500ms in step of 10ms.
