SEL-2431

Voltage Regulator Control

The SEL-2431 Voltage Regulator Control is compatible with most 32-step, single-phase voltage regulators manufactured in North America. Use various hinge and wiring kits to easily upgrade existing controls without removing the regulator from service, or order the SEL-2431 in a preconfigured enclosure for simplified installation. Quickly integrate the SEL-2431 into Ethernet or serial communications networks using fiber or copper options.

Optimize System Voltage—Control system voltage with directional voltage profiles and detailed tap change event reports.

Install Into Multiple Power System Types—Configure operating modes to fit your application: locked-forward, locked-reverse, idle-reverse, bidirectional, cogeneration, or FlexDG.

Apply in Systems With Multiple Sources Including Distributed Generation—FlexDG mode detects whether reverse power flow is coming from cogeneration/DERs or the traditional power source. It can use the change in voltage following a tap and the direction of current in deciding which side to regulate. Bias mode can be applied with FlexDG, cogeneration, and bidirectional modes to improve voltage regulation in low-current conditions.

Track Tap Position Accurately—Monitor motor current and holding switch status for accurate tap position tracking.

Monitor Motor Current—Monitor and troubleshoot your voltage regulator with recorded tap change motor current waveforms.

Integrate Into Distribution Automation Networks—Integrate the SEL-2431 into Ethernet or serial communications networks with DNP3, SEL, and synchrophasor protocols. Both the serial and the Ethernet ports are available with copper and fiber-optic connection options.

Reduce Commissioning Time—Accelerate installation and commissioning with application-specific settings. Regulate voltage, apply advanced metering, and implement event recording capabilities with fewer than 20 settings.

Quickly Retrieve Data—Event reports, tap change history, load profile data, and Sequential Events Recorder (SER) data are all available through the USB port or other communications interfaces. You may also use the USB port to quickly transfer settings, upgrade firmware, and expand onboard storage capacity.

Install Easily With a Purpose-Built Enclosure and 19-Pin Interface—The SEL-2431 outdoor enclosure can be mounted to a single-phase voltage regulator, pole-mounted for midline installations, or remotely mounted in distribution substations. With preconfigured options for precise-timing devices and radio-ready communications equipment, the SEL-2431 enclosure offers a modernization path for advanced distribution management systems (ADMSs) and system-level volt/VAR optimization. The optional 19-pin universal interface supports multiple voltage regulator models with a single interface.

Details

Built-In Reliability, Ten-Year Warranty
Reduce maintenance and repair costs with the industry’s only voltage regulator control with a worldwide, ten-year warranty.

Ethernet Communications
Quickly integrate the SEL-2431 into Ethernet or serial communications networks with DNP3, SEL, and synchrophasor protocols. The SEL-2431 comes standard with a copper or fiber serial communications card of your choice in Port 1. Populate Port 2 with another serial communications card or with a dual Ethernet communications card. Ethernet port options include copper and/or fiber.

USB Flash Drive Interface
Retrieve event reports, load profile information, tap history, and other system parameters with a USB flash drive. Stay connected to your system without a network for troubleshooting analysis and planning. The USB feature includes a secure authentication key, which is required for front-panel Level 2 access, reducing the risk of access by unauthorized personnel.

IEEE C37.118 Synchrophasors
Easily monitor your network with built-in IEEE C37.118 synchrophasors.
