Vectorical
Delta-I Type high resistive fault
selective relay. :
ADR219C
Back
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.
Specifications :
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.
