Transformer LTC Control
Configure parameters for bandwidth voltage control, tap duration, and tap delays. Control the LTC during forward power flow and reverse power flow conditions using locked-forward, locked-reverse, bidirectional, and cogeneration operating modes. The controller compensates for voltage drops on the line between the transformer and the load center. To force the LTC into a neutral position, use the run-to-neutral function. 

Cooling Bank Control
Improve energy efficiency by automating cooling systems to adapt to changing load and weather conditions. Automate fan and/or oil pump bank alternation and exercising to balance wear and prevent mechanical seizure.

Transformer Paralleling
Operate transformers in parallel by using up to four SEL-2414 controllers and using preconfigured Ethernet settings to coordinate tap positions and maintain voltage. Choose from leader/follower or current angle control methods for reliable transformer paralleling.

Transformer Monitoring
Use the SEL-2414 for thermal, through-fault, and voltage monitoring. Monitor up to 32 tap positions and up to 3 neutral LTC positions. Activate alarms based on the thermal condition of the transformer or other monitoring conditions. With tap-change limit and hunting alarming capabilities, the controller maintains voltage stability and prevents equipment damage. 

Flexible I/O for Local Control and System Applications
Choose I/O options that include digital inputs for statuses, such as oil level and sudden pressure, as well as load tap position control and monitoring; RTD inputs for measurements such as ambient, top-oil, and hotspot temperatures; digital outputs for control and alarms; analog inputs and outputs; and ac current and voltage inputs.  

Extensible Logic Engine
Customize your device with powerful math and logic. Use control equations with logic, arithmetic, analog comparison, edge-trigger, and timer functions for automatic local control and to combine data into system information. Time-deterministic, high-speed processing is ideal for time-critical applications. 

Critical Reporting and Logging
Store up to 1024 Sequential Events Recorder (SER) reports of digital input transitions, which are time-stamped to the nearest millisecond. Analyze SER reports, analog trending, and oscillographic event reports for rapid commissioning, testing, and post-event diagnostics. Trigger event reports of voltage, current, and Device Word bit status in EVE, CEV, and COMTRADE formats. 

Reliable Integration With SCADA
Flexible communications options provide reliable integration with SCADA. Choose preferred protocols from Modbus, DNP3, IEC 61850 Edition 2 (including mode behavior), the Parallel Redundancy Protocol (PRP), the Simple Network Time Protocol (SNTP), Precision Time Protocol (PTP), the Rapid Spanning Tree Protocol (RSTP), Telnet, Ethernet File Transfer Protocol (FTP), and SEL protocols like Mirrored Bits communications, SEL Fast Meter, SEL Fast SER, SEL ASCII, and binary communications protocols.

Rugged Hardware Design
Built to the same standards as SEL protective relays, the SEL-2414 withstands vibration, electrical surges, fast transients, and extreme temperatures, meeting stringent industry standards. For even harsher environments, order conformal coating for the printed circuit boards to provide an additional barrier to severe environments and airborne contaminants such as hydrogen sulfide, chlorine, salt, and moisture.

AC Metering Capabilities
Measure and record voltage, current, power, energy, power factor, and frequency; demand/peak demand metering; and maximum/minimum metering with extensive ac metering and monitoring capabilities. Apply values in programmable calculations and triggers within the meter.
