M-3410A Intertie/Generator Protection Relay
Description
The M-3410A Intertie/Generator Protection Relay is intended for the protection of the intertie between the
utility and dispersed generation. It is also suitable for the protection of synchronous and induction
generators. Communications and control features of the M-3410A are accomplished utilizing the M-3810A
IPScom®For WindowsTM Communications Software Package from a PC platform, or M-3811A IPScom For
Palm OS®running on a HandspringTM VisorTM or PalmTM Handheld.
Metering
The relay provides metering of voltages, currents, real power, reactive power, power factor, frequency and
positive sequence impedance.
Metering Accuracies are:
Voltage:0.5 V or 0.5%, whichever is greater (Range 0 to 600 V)
Current: 5 A rating, 0.1 A or 3%, whichever is greater (Range 0 to 14 A)
1 A rating, 0.02 A or 3%, whichever is greater (Range 0 to 2.8 A)
Power: 0.02 PU or 2%, whichever is greater
Frequency:0.03 Hz (from 57 to 63 Hz for 60 Hz models; from 47 to 53 Hz for 50 Hz models)
Oscillographic Recorder
The oscillographic recorder provides comprehensive data recording of all monitored waveforms, input
contacts and output contacts, storing up to 120 cycles of data. The total record length is configured for one
or two partitions. A programmable post trigger delay (5 to 95%) is incorporated to capture breaker
operation. The oscillograph is triggered either remotely using the serial interface, or designated status
input signals or M-3410A programmable output operations. Storage of oscillographic records is nonvolatile,
and will be retained even without power, as long as the on-board battery is healthy.
Oscillographic data can be downloaded using serial communication in Common Format For Transient
Data Exchange (COMTRADE) format as specified by IEEE Standard C37.111-1999.
Sequence of Events
A total of 32 nonvolatile events can be stored. The recorded information includes the function(s) operated,
the function(s) picked up, input/output contact status and time stamp. The events can be retrieved through
the communications port. After the 32nd event is stored, additional events result in the oldest event being
dropped (FIFO). The information is time-stamped to 1 ms resolution.
Calculations
Current and Voltage Values : Uses discrete Fourier transform (DFT) algorithm on sampled (32 times per
cycle) voltage and current signals to extract fundamental frequency phasors for calculations. The 59/27
function, when set for RMS measurement, uses a time domain algorithm to calculate the voltage
magnitude.

M-3410A Intertie/Generator Protection Relay
Sensing Inputs
3 Voltage Inputs : Rated nominal voltage of 69 V ac to 480 V ac, 60 Hz (50 Hz user configurable). Will
withstand600 Vcontinuous voltage. Sourcevoltages maybe line-to-groundor line-to-line connected.Phase
sequence ABC/ACB is selectable. Voltage transformer burden less than 0.25 VA at 120 V ac.
3 Current Inputs : Rated current (IR) of 5.0 A or 1.0 A, 60 Hz (50 Hz user configurable). Will withstand 2 IR
continuouscurrentand30IRfor2seconds.Currenttransformer burdenislessthan0.75 VA at5Afor5A inputs,
0.3 VA at 1 A for 1 A inputs.
Control/Status Inputs
The control/status inputs, INPUT1 and INPUT2, can be programmed to block any of the M-3410A functions
and trigger the oscillograph recorder. The control/status inputs accept only dry contacts and are internally
wetted (9 V dc) by the relay's power supply. A minimum current of 1.3 mA is required to avoid spurious
triggeringof the input.
Output Contacts
The two programmable output relays, each with a contact are rated as per ANSI/IEEE C37.90-1989 for
tripping: make 30 A for 0.2 seconds. Available hardware configurations include two normally open (Option
B1), one normally open and one normally closed (Option B2), or two normally closed (Option B3) contacts.
The contacts will carry 8 A, break 6 A at 120 V ac, break 0.1 A at 125 V dc, inductive break 0.1 A. Also
provided is a self-test alarm output contact (form 'c') with a rating of 8 A at 120 V ac, 5 A at 30 V dc, 125 V
dc 0.15 A resistive, 0.1 A inductive.
Any of the M-3410A protective functions can be individually programmed to activate the two programmable
outputs.The user canconfigure the twoprogrammable outputs toeither energize orde-energize to issuean
outputcommand.
The outputs (excluding the self-test) can have two modes of operation, LATCHING and NORMAL. The
LATCHINGmode requires anoperator interventionto deactivatethe outputs afterthe conditionfor operation
has been removed. In the NORMAL mode, when the condition for tripping has been removed, the output(s)
will deactivate automatically after the corresponding seal-in timers have expired.
Target/Status Indicators and Controls
The RELAY OK LED reveals proper cycling of the microprocessor. The DIAGNOSTIC LED provides
indicationof theerror code(whenflashing). TheOSC TRIGGER LED indicatesthat theoscillographhas been
triggered. The remaining eleven LEDs are used to indicate which protective function(s) have been tripped.
OUTPUT 1 and OUTPUT 2 are used to indicate the status of the output contacts. The output LEDs will
illuminate when the output contact relays are tripped. The TARGET/OUTPUT RESET button resets the
target LEDs if the conditions causing the operation have been removed. Holding the TARGET/OUTPUT
RESET buttondisplays the presentpickup statusof the M-3410Afunctions. TheTARGET/OUTPUT RESET
button will deactivate the tripped output contact if the LATCHING mode was selected. (If the seal in timer
has already expired, the output contact will deactivate immediately.)
Communication
Communicationsports include afront panel RS-232port and a rear portuser configurable toRS-232 or RS-
485. The RS-232 ports are connected physically with a DB-9 connector and the RS-485 port utilizes 4-wire
interfacemounting screw terminals.
M-3810A IPScom®For WindowsTM or M-3811A IPScom For Palm OS®Communications Software utilizing
the MODBUS communications protocol in RTU mode, implements serial, byte-oriented asynchronous
communication with the M-3410A and provides the following functions:
• Interrogationand modification of setpoints
• Time-stamped sequence of events information for the 32 most recent events
• Real-timemetering of allquantities measured
• Downloadingof recordedoscillographic data
• RelaySetup
