Protection functions Overview
Non Directional Over Current
Protection (50/50N/51/51N):
The core functionality of ADR244A relay is
equipped with multi function feeder
protection. The relay provides Non
Directional phase and ground over current
protection with multiple settings (Two stages
for phase over current and ground over
current) for various power system
applications and wide range of protection
settings. The function is equipped with digital
filter algorithms, providing the rejection of
higher harmonics & DC offset. Selectable
IEC / IEEE inverse time curves & user define
curve with non directional over current
protection will be providing greater
selectivity, flexibility and sensitivity to users
for better relay co-ordinations.
ADR244A relay provides inverse time over
current characteristic for phase and ground
over current elements. Each stage of phase
and ground over current elements are

independently settable with inverse time or
definite time characteristic. The following
tripping characteristics are available;
IEC/IEEE Inverse curves for tripping of over current
elements
ADR244A relay provides the inverse time
dropout characteristic (electromechanical
relay reset) for IEEE curves. The output of
protection function shall be reset after
dropout time delay.
ADR244A relay provides two stages of
definite time/inverse time internally derived
zero sequence over current (3I0>) protection
to detects asymmetrical faults in electrical
network. It can apply to over head
transmission line, underground cable, and
feeder. The ground current (3I0>) calculated
from three line currents.
Internally derived residual over current application
ADR244A relay provides two stages of
externally ground over current protection.
ADR244A relay measures ground fault
current through neutral CT input. Externally
ground CT input can also apply for high
impedance restricted earth fault protection or
sensitive ground fault protection through
CBCT.

Externally measured ground over current through CBCT
Harmonic blocking / Unblocking for
Over Current Protection
(50H/51H/50NH/51NH):
Harmonic blocking / unblocking feature
equipped in ADR244A relay provides stability
on inrush current during transformer
energization. Harmonic blocking/unblocking
feature is independent for each stage of
phase and ground over current protection.
Additional functions (CLP & SOTF):
ADR244A provides the cold load pick up
(CLP) and switch on to fault (SOTF) as
additional functions. User can select the one
of this function for application. Cold load pick
up function provided in relay for multiple
applications. The application of this feature
can be use to avoid wrong operation on
inrush current during transformer
energization without compromising sensitivity
of over current protection.
The ADR244A provides SOTF function to
protection feeder against switch on to fault
condition during feeder/transformer
energization.
Negative Phase Sequence Over
Current Protection (46):
Two independent stages of Definite and
Inverse time Negative sequence over current
protection will be providing back up
protection of over head transmission line /
underground cable / feeder against
unbalanced faults, very high resistive
phase/ground faults and unbalanced loads.

Protection can also apply in condition when
there is a very high resistive ground fault and
ground element may not sense the fault
current.
The negative phase sequence over current
element can be programmed as IDMT or
definite time characteristic. ADR244A relay
provides ten selectable IEC / IEEE inverse
curves and one user define curve for each
stage.
Broken Conductor Protection (46BC):
ADR244A equipped with broken conductor
detection protection. Broken conductor
condition can be detected by ratio of
Negative sequence current to Positive
sequence current (I2/I1) provides higher
sensitivity on High resistive fault.
Thermal overload Protection (49):
ADR244A relay provides thermal over load
protection of transformer against over load
conditions. Relay estimate thermal contents
and initiate alarm & tripping if the thermal
contents are higher than the preset value.
Trip time of relay follows the according to the
thermal time constant value set in to relay.

Breaker Failure detection (50BF):
If the fault current is not interrupted after a
time delay expired, circuit breaker failures
detected, and execute trip command to
upstream circuit breaker. ADR244A relay
incorporates circuit breaker failure protection
to detect failure of tripping command
execution due to mechanical or electrical
problems in circuit breaker.
Under current detection (37):
ADR244A provide under current protection
with definite time delay option.
Trip circuit supervision (74T):
Any binary inputs for circuit breaker poles
can be used for monitoring the circuit
breaker trip coils including connecting
cables. Relay initiate alarm whenever the
circuit breaker control/DC circuitry gets
interrupted.
The ADR244A is having 4 separate digital
opto-coupler status input which can be used
to continuously monitor heartiness of trip-
circuit.
Relay monitor Trip coil continuity through CB
NO during close condition and through CB
NC during Trip condition. If any discontinuity
observed it generate Alarm signal.
Programmable Inputs, Outputs &
Logic:
The ADR244A relay equipped with 7 nos. of
programmable digital outputs and 4 nos. of
optically isolated digital inputs. All 4 nos. of
digital inputs are the programmable digital
inputs to be configured for desired

Programmable LEDs and
Pushbuttons:
The ADR244A relay provides total 4 nos. of
target & programmable LEDs with dual
colors indication. The LEDs can be
programmed either through HMI or through
PC software (RTV2 software).
