SEL-734 Capabilities
Accurate Revenue Metering
The SEL-734 exceeds ANSI C12.20 0.2 and IEC 62053-22 0,2 S
accuracy class requirements. Transformer/line-loss compensation
adds to meter accuracy when the meter location and billing points
differ. ACSELERATOR QuickSet Software provides a simple test
mode interface to easily verify meter accuracy.
Communications and I/O
Select from seven communications ports and eight communications
protocols, including 10/100BASE-T or 100BASE-FX Ethernet.
Advanced communications and protocols, such as DNP3, reduce
the need for analog and digital outputs. When installations must
communicate with legacy equipment, SEL offers digital and analog
output options for the SEL-734. The SEL-2800 Fiber-Optic Transceivers provide electrically isolated communications paths between
EIA-232 ports.
Load Profile Recorder
Twelve independent load profile recorders in the SEL-734P allow
simultaneous meter and power quality logging of up to 192 data
channels. Select up to 16 channels per recorder and sample rate
SEL-734 Data Sheet
intervals from 3 seconds to 60 minutes. Trend averages, minimum, maximum, changes, and snapshots at a rate of once every
three seconds.
ACSELERATOR QuickSet offers a fast and simple method to
retrieve, plot, and export load profile data to .HHF or .CSV formats.
Itron MV-90 meter reading software communicates to any SEL-734
communications port and automates meter reads for large-scale
metering installations.
Save LDP data in .HHF or .CSV formats.

waveform captures of
system anomalies.
VSSI reports detail system
interruptions with 1 ms resolution.
* SEL-734P benefits
VSSI Recorder
Correlate system disturbances with the voltage sag/swell/interruptions (VSSI) recorder. Enabled from the factory, the VSSI recorder
time-stamps voltage excursions with up to 1ms resolution and
records indefinitely using an adaptive sampling rate. The SEL-734
stores and reports residual voltage, duration, affected phases,
CBEMA/ITIC reports, and time stamp of occurrence. The VSSI settings include trigger thresholds from ±1% to ±95% of the actual
value and automatic recording duration dependent on the length of
the voltage excursion. ACSELERATOR QuickSet automatically
graphs and analyzes VSSI data, and includes an export feature.
Applications with SCADA systems can also retrieve these data
using the DNP3 protocol.

TOU Metering
Record demand and energy consumption with a user-defined calendar; use TOU metering to bill consumption at different rates based
on season, day type, and time of day. The program automatically
self-reads and resets demand; there is no need to manually reset
meters.
Harmonic Metering
Monitor, record, and control using individual harmonic values,
THD, and K-factor with resolution up to the 50th harmonic.
Interharmonic Metering
Measure, record, and control using Group THD. Measure interharmonics from 20 Hz to 3285 Hz in 5 Hz bins.

Synchronized Phasor Measurement
Combine the SEL-734 with an SEL IRIG-B time source to measure
the system angle in real time with a timing accuracy of ±10 µs. Measure instantaneous voltage and current phase angles in real time to
improve system operation with synchrophasor information. Replace
state measurement, study validation, or track system stability. Synchronized phasor measurements use the SEL Fast Message synchrophasor protocol and exceed the Level 0 accuracy requirements
defined by IEEE C37.118–2005.
Use SEL-5077 SYNCHROWAVE® Server Software* or SEL-5078
SYNCHROWAVE Console Software* to view system angle at multiple locations for precise system analysis and system-state measurement, shown to the right.
View system angle at multiple locations.
*Additional cost software.
Predictive Demand
The predictive demand function monitors accumulated demand and
alarms when the demand exceeds a user-defined limit. The SEL-734
can then shut down loads or peak-shave with generation to avoid
demand charges as shown to the right. The predictive demand alarm
is available through Modbus, DNP, MIRRORED BITS communications, or the front-panel LEDs.
Frequency Recording
Measure frequency for local and remote indication or use in control
and data acquisition. Use a load profile recorder for a “strip chart”
record of the frequency as often as every three seconds.

and maximum voltage, current, and power measurements. Use this
capability for equipment selection, troubleshooting, and diagnosis of
any installation.
Capture minimum/maximum quantities with 25 ms resolution.

SEL-734 Capabilities (Continued)
Logging and Recording
Store a minimum of 16,000 sequential events records capturing any
power quality disturbance. Retrieve data using ACSELERATOR
QuickSet software, Modbus, DNP3, or ASCII. Store and analyze
waveform capture data using ACSELERATOR QuickSet.
Automatic Event Reporting
After recording an event report, the SEL-734 can automatically
report event data through SEL or DNP3 protocols to a communications master. SEL-5040 software can automatically collect SEL-734
waveform data without the need for manual retrieval.
Password Protection
Three password levels ensure protection of critical meter configuration and billing data. Password levels include read only, limited
read/write, and full read/write capabilities.
Monitor device and power system events
with the Sequential Events Recorder (SER).
Programmable Logic (SELOGIC Control Equations)
The meter provides user-programmable logic to combine meter calculations, contact inputs, remote command inputs, and timers to
control internal logic and contact outputs. The logic allows the following operations:
• Logic (OR, AND, NOT)
• Math (+, —, x, /)
• Analog compare (>, <, <>, =, =, =)
• Triggers (RISING EDGE, FALLING EDGE)
• Sixteen latches
• Sixteen remote-control logic units
• Sixteen programmable logic variables with pickup and
dropout timers
• Sixteen programmable analog variables
