SEL-734B

SEL-734B

Advanced Monitoring and Control System

The SEL-734B with low-energy analog (LEA) inputs provides advanced monitoring and control capabilities for applications, such as capacitor bank control and feeder monitoring. LEA sensor compatibility allows safe, fast, and inexpensive installations. Advanced communications report data to SCADA systems and allow remote operations from a control center.Order enclosures with preloaded control schemes or design custom controls, such as capacitor bank controllers or sectionalizers, using acSELerator QuickSet SEL-5030 Software templates. SEL capacitor bank control and sectionalizer templates improve efficiency, increase reliability, and reduce installation time and maintenance costs. User-customized templates add flexibility, improving any smart grid installation.

Capacitor Bank Control

Choose capacitor bank switching strategies for voltage, kVAR, current, and power factor control with the SEL-734B. Easily toggle control strategies, such as between SCADA and automatic control, from the control center with DNP3 binary objects. Implement a SCADA heartbeat to switch to islanded automatic control if SCADA communication is lost. Customizable logic allows you to modify and create control schemes to adapt to your application.

Complete Automation

Order the SEL-734B preprogrammed for capacitor bank control, or customize it to suit virtually any need. Program the SEL-734B for sectionalizing, feeder monitoring, overcurrent detection (for use in locating faults), or virtually any other application demanded. Thirty-two SELogic control equation elements allow powerful control and monitoring schemes. With features from the SEL-734 Revenue Meter included, the SEL-734B offers the most flexible monitoring and control solution on the market.

Time- and Temperature-Based Switching

Use the SEL-734B for time- and temperature-based switching now, and easily upgrade to advanced switching control based on power factor or VARs in the future.

Individual-Phase Switching

The full-size enclosure option enables the addition of three-phase voltage sensing via PT inputs. Combined with LEA current sensing via line post sensors, this gives the SEL-734B the ability to switch each phase individually.

Plug-and-Play Connections

Choose from multiple enclosure styles, various sensor input ranges, and customizable enclosures to make the SEL-734B a plug-and-play device. The SEL-734B is offered as a standalone device or is installed in a compact or full-sized enclosure with a variety of connections. Make your commissioning a plug-and-play experience with the SEL-734B.

SEL-734B Details

The SEL-734B delivers leading-edge control to any distribution system. The following list highlights some of the unique benefits and capabilities of the SEL-734B.Install the SEL-734B in applications that require conventional or LEA sensors.
  • 120 or 25 V voltage input ranges.
  • 10 V LEA or magnetic current transformer (CT) inputs.
Monitor, trend, and log system conditions.
  • Monitor active and reactive forward and reverse power flow.
  • Trend power system conditions with up to 192 recording channels.
  • Log years' worth of data at acquisition rates as fast as 3 seconds.
Increase system accuracy and versatility with Instrument Transformer Compensation (ITC).
  • Compensate for both phase and ratio errors over six calibration points to get the most accuracy from your instrument.
  • Shift the measured signal up to ±180º. The SEL-734B can compensate for this phase shift.
Detect high-distortion conditions with harmonic triggers up to the 50th order.
  • Configure independent thresholds to target specific harmonic components.
  • Map the triggers to the front-panel LEDs or configure the scrolling LCD to quickly alert local operators.
  • Add harmonic binary triggers and analog quantities to the DNP3 or Modbus map to inform SCADA operators.
  • Start an oscillography waveform recording when the harmonic trigger asserts for postanalysis.
  • Analyze detailed harmonic data easily through the front-panel menu or the human-machine interface (HMI).
Design
Custom control schemes with programmable SELogic and acSELerator QuickSet design templates.Reliability
Backup radios, gateways, or other accessories with an integrated 30 or 40 W, 15 Vdc power supply/backup.
