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's 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.
Backup Power for Distribution Controllers—Select the supercapacitor backup option, available in the full-size outdoor enclosure, to provide short ride-through power to the SEL-734B and 15 Vdc accessories during power losses, allowing enough time for radios to transmit event messages. The module will power a 24 W load during main power losses for approximately 90 seconds. The installed 58F supercapacitor stores approximately 1 Wh of usable energy.
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.
The 12" x 10" compact outdoor enclosure allows you to install the SEL-734B practically anywhere. Additionally, the enclosure contains a removable tray that allows you to easily mount a radio inside.
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.
