Protection Features
Multiple Options
Several option for protection &
communications are provided to match
basic to high end application requirements.
Protection
The 350 feeder protection system offers
protection, control and monitoring in one
integrated, economical and compact
package.
Timed Overcurrent (Phase, Ground,
Neutral)
The 350 has three-phase TOC elements
which enables coordination with upstream
and downstream protection devices such
as fuses, overload relays, etc to maximize
fault selectivity and minimize interruptions
and downtime.
Multiple time current curves are available
including IAC, IEC, ANSI and IEEE curves.
Additional user programmable flex curves
can be used to customize and meet
specific coordination requirements. The
TOC has both linear and instantaneous
reset timing function to coordinate with
electro-mechanical relays
Instantaneous Overcurrent (Phase,
Ground, Neutral)
The instantaneous element provides
fast clearance of high magnitude
faults to prevent damage to the power
infrastructure and the equipment
connected to it.
Enhanced Diagnostics
Preventative Maintenance
The 350 allows users to track relay exposure
to extreme environmental conditions by
monitoring and alarming at high ambient
temperatures. This data allows users to
proactively schedule regular maintenance
work and schedule upgrade activities.
The diagnostics data enables the user to
understand degradation of electronics due
to extreme conditions.
Cost Effective
Robust Design
The 350 is subjected to Accelerated
Life Testing (ALT) to validate accurate
relay function under specified normal
conditions. The device is further tested for
durability through Highly Accelerated Life
Testing (HALT) where it undergoes extreme
operating conditions. The robust 350
design ensures long term operation.
Reduced Life Cycle Cost
The 350 is designed to reduce total
installation and life cycle cost for feeder
protection. The draw out construction
of the device reduces downtime during
maintenance and decreases extra
wiring needed for relay testing and
commissioning.
Neutral Overcurrent
The neutral signal is derived as the residual
sum of the three phase CTs eliminating the
need for an additional ground sensor.
Sensitive Ground Overcurrent
Sensitive ground protection feature
detects ground faults on high impedance
grounded systems in order to limit damage
to conductors and equipment. Special
low ratio CT’s are used for this purpose to
detect low magnitude ground faults.
Over/Under Voltage Protection
Overvoltage / Undervoltage protection
features can cause a trip or generate
an alarm when the voltage exceeds a
specified voltage setting for a specified
time.
Frequency Protection
The 350 offers overfrequency and
underfrequency elements to improve
network (grid) stability using voltage
or frequency based load shedding
techniques.
It also provides back up protection when
protecting feeders and other frequency
sensitive power equipment.
Arc Flash Mitigation
The 350 relay is equipped with multiple
setting groups and two user definable
inverse curves -FlexCurves A and B for
fast and reliable arc-flash mitigation and
breaker operation. In the event of an arc-

flash, the relay can be set to communicate
to any upstream or downstream devices
via IEC 61850 GOOSE messaging.
Cable Thermal Model
The cable thermal modelelement protects
feeder cables against overheating due
to excessive load. It estimates the
temperature rise of current carrying
conductors based on the amount of
current flow (I2R) and alarms when
temperature rise exceeds a threshold
value. This protection feature is essential
to ensure the longevity of electrical
feeders; particularly important to prevent
premature cable failures, expensive repair
costs and system down time.
Neutral/Ground Directional
Overcurrent
The directional ground overcurrent isolates
faulted feeders in ring bus or parallel feeder
arrangements. It also allows detection of
back feed of fault current from feeders
with motors.
Control
Cold Load Pick Up
Cold Load Pick up allows automatic or
manual blocking or raising of trip settings
for a period after the breaker has been
closed. This feature adapts the pick up
of overcurrent elements to override the
higher overload currents resulting from
re-energization of feeder after a long
period of time.
Breaker Failure
The Breaker Failure function is used to
determine when a trip command sent to
a breaker has not been executed within
a selectable time delay. In the event of
a breaker failure, the 350 will issue an
additional signal to trip the breakers
connected to the same busbar or signal
the trip of upstream breakers.
Autoreclose
Reclose can be initiated externally or from
an overcurrent protection. Up to four
reclose operations are available, each
with a programmable dead time. For each
reclose shot, the relay can be programmed
to block any overcurrent element.
Automation and

Distribution Feeder Protection
Logic Elements
The 350 relay has sixteen Logic Elements
available for the user to build simple
logic using the state of any programmed
contact, virtual, remote input or the output
operand of a protection or control element.
The logic provides for assigning up to three
triggering inputs in an “AND/OR” gate for
the logic element operation and up to
three blocking inputs in an “AND/OR” gate
for defining the block signal. Pickup and
dropout timers are available for delaying
the logic element operation and reset
respectively.
Virtual Inputs
Virtual inputs allow communication devices
the ability to write digital commands to
the 350 relay. These commands could be
open/close the breaker, changing setting
groups, or blocking protection elements.
Multiple Settings Group
Two separate settings groups are stored in
nonvolatile memory, with only one group
active at a given time. Switching between
setting groups 1 and 2 can be done by
means of a setting, a communication
command or contact input activation.
The two settings groups allow users to store
seasonal settings- such as for summer and
winter or alternate profiles such as settings
during maintenance operations.
Monitoring & Diagnostics
Event Recording
Events consist of a broad range of change
of state occurrences, including pickups,
trips, contact operations, alarms and self
test status. The 350 relay stores up to
256 events time tagged to the nearest
millisecond. This provides the information
required to determine sequence of
events which facilitates diagnosis of relay
operation. Event types are individually
maskable in order to avoid the generation
of undesired events, and includes the
metered values at the moment of the
event.
Oscillography/ Transient Fault
Recorder
The 350 captures current and voltage
waveforms and digital channels at 32
samples per cycle. Multiple records can
be stored in the relay at any given time
with a maximum length of 192 cycles
Oscillography is triggered either by internal
signals or an external contact.
Trip/Close Coil Monitoring
The 350 can be used to monitor the
integrity of both the breaker trip and closing
coils and circuits. The supervision inputs
monitor both the battery voltage level,
while the outputs monitor the continuity of
the trip and/or closing circuits, by applying
a small current through the circuits.
Basic Metering
Metered values include:
• Current:Ia,Ib,Ic,In,Ig,Isg
• Phase-to-phaseandphase-to-ground
voltages for bus and line: Van, Vbn, Vcn,
Vab, Vbc, Vca
• Activepower(3-Phase)
• Reactivepower(3-Phase)
• Frequency
Advanced Device Health
Diagnostics
The 350 performs comprehensive device
health diagnostic tests during startup
and continuously at runtime to test
its own major functions and critical
hardware. These diagnostic tests monitor
for conditions that could impact system
reliability. Device status is communicated
via SCADA communications and the front
panel display. This continuous monitoring
and early detection of possible issues helps
improve system availability by employing
predictive maintenance.
IRIG-B
IRIG-B is a standard time code format
that allows time stamping of events
to be synchronized among connected
devices within 1 millisecond. An IRIG-B
input is provided in the 350 to allow time
synchronization using a GPS clock over a
wide area. The 350 IRIG-B supports both
AM and DC time synchronization with
an auto detect feature that removes the
requirement for manual selection.

Password Control
With the implementation of the Password
Security feature in the 350 relay, extra
measures have been taken to ensure
unauthorized changes are not made to
the relay. When password security is
enabled, changing of setpoints or issuing
of commands will require passwords
to be entered. Separate passwords
are supported for remote and local
operators, and separate access levels
support changing of setpoints or sending
commands.
Advanced
