Advanced Asset Monitoring
Monitor critical substation assets with comprehensive transformer thermal and through-fault monitoring. Calculate top oil, hotspot, insulation aging acceleration factor, and loss-of-life while generating hourly and daily data about your transformer. Capture through-fault current data that could lead to increased transformer wear. Assert alarms based on the thermal condition of the transformer or on other monitored conditions.

Flexible I/O for Local Control and System Applications
Choose I/O options that include digital inputs for status, such as oil level and sudden pressure, as well as load tap position control and monitoring; RTD inputs for such measurements as ambient, top-oil, and hot-spot temperatures; digital outputs for control and alarms; analog inputs and outputs; and ac current and voltage inputs. Easily program monitoring and control functions with powerful logic, math, timers, counters, and edge-trigger functions. These features allow easy integration with new and retrofit transformer monitor applications.

Local Control With SELogic Control Equations
Easily program 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.

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.

Critical Reporting and Logging
Store up to 512 Sequential Events Recorder (SER) reports of digital input transitions, time-tagged 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. Store analog quantities at customizable intervals using the Analog Signal Profile. Send the SER data to a communications processor or computer for system analysis.

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

Simple Commissioning Tools
Easily set with acSELerator QuickSet SEL-5030 Software. The front-panel HMI provides complete configuration access and displays settings, measurements, and calculated values. Store transformer parameters in nameplate.txt files and nameplate and test data configurations with QuickSet.

High Reliability, Rugged Design, and Low Price
Built to the same high standards as SEL protective relays, the SEL-2414 withstands vibration, electrical surges, fast transients, and extreme temperatures, meeting stringent industry standards. Compare our specification compliance, higher reliability, price, and worldwide, ten-year warranty to other transformer monitors. For even harsher environments, order conformal coating for the printed circuit boards to provide an additional barrier to harsh environments and airborne contaminants such as hydrogen sulfide, chlorine, salt, and moisture.
