ADR213B
second generation Numerical
Transformer Protection Relay for Traction
Application. It consist all the necessary protection
and monitoring functions required for traction feeder.
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 0.5VA).
Online display of Primary current i.e.
load
current and unbalance current.
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 Transformer
Protection. As per RDSO specs
TI/SP/PSI/PROTCT/4050
Dual Slop characteristic for excellent
through fault stability.
Operation based on fundamental frequency
value.
Harmonics Restrain for Tx charging and CT
saturation condition.
