Accurate, Bidirectional Metering:
Exceeds ANSI C12.20 0.2 and IEC 62053-22 0,2 S accuracy class bidirectional, with full four-quadrant energy metering for generation, interchange, transmission, distribution, or industrial applications.

Standard Software Tools:
Easily configure, test, monitor, and retrieve data using acSELerator QuickSet® SEL-5030 Software. acSELerator QuickSet quickly programs, retrieves, plots, and exports billing data to .HHF or .CSV formats.

Transformer and Line-Loss Compensation:
Enter transformer nameplate and line impedance information directly into the meter to automatically compensate for transformer or line losses and move the billing point.

Power Quality Monitoring:
Record voltage sag/swell/interruption (VSSI), monitor harmonics, capture waveforms, measure flicker, and record sequential events.

High-Speed Load Profile (LDP) Data Recorders:
Multiple LDP recorders store billing and power quality data in separate records with a maximum update rate of once every three seconds. acSELerator® QuickSet® quickly retrieves, plots, and stores LDP data to a laptop computer or remotely over any communications port resets.

Time-of-Use (TOU) Metering:
Provides flexible, time-differentiated energy and demand registers, with multiple day types, rates, seasons, and a 20-year programmable calendar. Automation functions include programmable self-reads and peak demand resets.

Complete Automation:
Customize alarms and automate control based on measured load information using advanced SELogic® control equations. Integrate with communications processors for single-point station access.

 

Legacy SEL-734 Revenue Meter

Ordering Information

Budgetary Price:
$1,594

The Legacy SEL-734 Meter exceeds ANSI and IEC Class 0.2 accuracy with four-quadrant energy and demand metering. Advanced load profile trending compatible with MV-90®, DNP3, and Modbus® protocols ensures integration with practically any billing system. In addition to a full set of revenue metering features, advanced power quality monitoring will report costly system disturbances.

 

  • Accurate Metering
    Exceeds ANSI C12.20 0.2 class accuracy at unity power factor with bidirectional, full four-quadrant energy metering for generation, interchange, transmission, distribution, or industrial applications.
  • Load Profile Data Collection
    Collect billing data with a simple-to-use load profile recorder that captures years of data.
  • 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 angles in real time to improve system operation with synchrophasor information.

  • Transformer and Line-Loss Compensation
    Enter transformer nameplate and line impedance information directly into the meter to automatically compensate for transformer or line losses and move the billing point.
  • Time-of-Use (TOU) Metering
    Provides flexible, time-differentiated energy and demand registers with multiple day types, rates, seasons, and a 20-year programmable calendar.
  • 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. The predictive demand alarm is available through Modbus, DNP3, Mirrored Bits® communications, or the front-panel LEDs. 
  • Options:
     

    • Copper or fiber-optic Ethernet ports
    • Horizontal or vertical mount
    • 125/250 Vdc/Vac or 24/48 Vdc power supply
    • KYZ output card
    • Current class 2, 10, or 20
    • Conformal coating 
    • Telephone modem, EIA-232 and EIA-485 ports
Flexible Mounting Options

A variety of bezels, brackets, enclosures, and rack-mount kits are available for quick, easy, and clean-looking retrofit installations and mounting flexibility.
