E. Commonly Used Configuration Settings
Thissectionoutlinescommonlyusedmeterconfigurationsettings,including:MeterandTerminalIdentifier,
Current and Potential Transformer Ratios, Demand Metering, KYZ Pulse, Daylight Savings Time, Load
Profile, Front Panel Display, and Communications.
1. General Settings
The General Settings include the MID Meter Identifier,TID Terminal Identifier, and Current and Potential
Transformer Ratios (CTR and PTR).
To access General Settings, expand Group 1>Set 1>General Settings from the a c SELE r a t o r QuickSet settings
editor tree.
a. MID and TID Settings
Meter reports include the MID and TID
for easy meter identification. These
configuration settings help uniquely
identify each meter within a system.
b. Current and Potential Transformer Ratios
The CTR and PTR configuration settings scale
the following meter reports from secondary to primary
quantities:
–MeterReports(MET)
–MeterandControlInterface(HMI)
–LoadProfile(LDP)
–DisplayPoints(DP)
–DistributedNetworkProtocol(DNP)
– Front-Panel LCD
Modbus®and SELo g i c ®control equations are
secondary quantities and are unaffected by CTR
and PTR values.
To set the CT and PT ratios, choose Group 1>
Set 1>General Settings from the a c SELE r a t o r
QuickSet settings editor tree. Note that the CTR
and PTR values are net ratios. For example, a
1200:5CTratioequatestoaCTRsettingof240.

TheSEL-734internaltimeclockisaccurateto100secondspermonth.Useoneofthemethodslisted
below to improve time-clock drift.
–ConfigureMV-90tosettheclockduringeveryread.
– Connect an SEL communications processor to Port 3.
– Set the time periodically using the DNP or Modbus protocol.
– Set the time with a c SELE r a t o r QuickSet Software.
–ConnectanIRIG-Btime-codeinputtothe2-pinterminalonthebackoftheSEL-734.SeeFigure2.

To enable DST, choose Daylight Savings Time from the a c SELE r a t o r QuickSet
settings editor tree and select Enable Daylight Savings Time Settings. Enter or
accept the default Start Time and Stop Time, then click Start Dates and Stop Dates
to select the present DST schedule.
If the meter is connected to an external time source, disable the DST setting in the SEL-734 to avoid
time-source conflicts.
c. Time Configuration Settings With MV-90
If using the Auto TimesetoptionasanMV-90MasterFilesetting:
– Disable the Enable Daylight Savings option in the SEL-734.
– Do not connect an external time source. This keeps the meter clock synchronized with the PC
clockandMV-90.

6. Load Profile (LDP) and MV-90
TheSEL-734Psupportsupto24LDPchannels,withanacquisitionrateof3–59secondor1–60minute
intervals. The Load Profile Settings LDLIST tool presents a list of all available LDP values.
Meter reading software built into a c SELE r a t o r QuickSet quickly retrieves, graphs, and exports LDP data
ineither.HHFor.CSVformat.Inaddition,third-partymeterreadingsoftware,suchasMV-90fromItron,
can automatically read LDP data from the SEL-734. The data are also available through the SEL YMODEM,
Modbus,andDNPprotocols.SeeSection9,page13fordetailsonconfiguringtheSEL-734forMV-90

V. Human-Machine Interface (HMI)
The a c SELE r a t o r QuickSet HMI displays
instantaneous meter information, captures reports,
and allows test and control of the SEL-734. To access
the Meter and Control interface, choose
Tools>HMI>HMI in the main a c SELE r a t o r
QuickSet window.
To maneuver through the windows, click on the HMI
tree-view list until the required display appears on the
right-handside.PressF1intheHMIwindowtoview
help on each interface.
A. Device Overview
The Device Overview window simulates the
front-panel interface of the SEL-734 and updates
approximately every second. This window displays
instantaneous metering information, and contact
I/O and front-panel LED status.
B. Phasors
Phasor diagrams are a powerful troubleshooting tool. Technicians and
engineers can quickly determine and resolve wiring issues at a glance.
This section contains phasor diagrams from three example installations.
Example 3 depicts a phasor diagram from a properly wired installation.
Examples4and5depictthemostcommonwiringissues.
1. Example 3, Correct Phase Rotation:

3. Example 5, Reversed CT Connections:
Many times CT polarity convention varies from site to site, which can
lead to reversed CT connections. The top label of the SEL-734 indicates
CT polarity convention with a dot that denotes current flow out of the
instrumentation transformer and into the SEL-734 CT terminal.
Figure25illustratesthephasordiagramofabalanced,three-phase

respect to their phase voltages. The SEL-734 incorrectly registers watt-

C. LDP and SSI
The a c SELE r a t o r QuickSetHMIdisplaysLoadProfileandVoltageSag/Swell/Interruptionreports.
To capture any of these reports, select the required date range and click Export.
1. Load Profile (LDP)
The meter adds an entry to the load profile
recorder at the interval set by the LDAR setting.
This entry contains the time stamp, the present
value of the selected LDLIST analog quantities,
and a checksum.
2. Voltage Sag/Swell/Interruption (SSI)
The SEL-734 Meter records voltage sags, swells,
andinterruptionswith1msaccuracy.Enable
andconfigureSSIintheVoltageSag/Swell/
Interruption Settings window of a c SELE r a t o r
QuickSet Software.
D. Test Mode
The a c SELE r a t o r QuickSet HMI allows simple test mode interaction
and eliminates the need to navigate through the front panel to
enable test mode. While in test mode, the SEL-734 stops collecting
LDP and Demand data and places an asterisk next to records in the
LDP report.
To place the meter into test mode, select a
Test Mode Quantity from the drop-down
box and click Enter Test Mode. The test mode
window depicts an optical port that pulses a
redtestpulseinconjunctionwiththeactual
front optical port. Click Exit Test Mode at the
end of an accuracy test to restore normal
meter operation.
E. Control Window
The control window provides an interface to set the date and time,
reset data, and test output contacts. For example, to set the time,
click Set next to the Time edit box to update the time in the meter.
a c SELE r a t o r QuickSet Software prompts

VI. Security and Passwords
A. Security
The SEL-734 supports four access levels to prevent unauthorized entry. The table below describes the default
passwords and the capabilities of each access level. The user must enter the ACC access level before entering
theEACor2ACaccesslevels.

B. Changing Passwords
To prevent unauthorized access, set strong passwords as described in the steps below. For example, the
password “OTTER” is weak because it is a six-character word found in the dictionary. The password
“O # h”pVw & ” is strong because it is random, undefined,
and contains eight characters.
