Advanced Asset Monitoring. Monitor critical substation assets with comprehensive transformer thermal and
through-fault monitoring. Calculate top oil, hot-spot, insulation aging acceleration factor, and loss of life while
generating hourly and daily data about your transformer. Capture the maximum/minimum values of all trans-
former model quantities. Capture through-fault current data that could lead to increased transformer wear.
➤ Critical Reporting and Logging. Store as many as 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. Send the SER data to a communications pro-
cessor or computer for system analysis.
➤ Communications and Integration. Automate fan bank control with flexible communications options that provide
easy integration with SCADA. Choose from single and dual Ethernet, Modbus
®
TCP, DNP3 LAN/WAN,
IEC 61850 Ed. 2, Modbus Serial, EIA-232, EIA-485, Telnet, and File Transfer protocols.
➤ AC Metering Capabilities. Take advantage of extensive ac metering and monitoring capabilities. Voltage, current,
power, energy, power factor, frequency; demand/peak demand metering; and maximum/minimum metering are
measured and recorded. Values can be used in programmable calculations and triggers within the meter.
➤ Simple Commissioning Tools. Make use of a front-panel HMI that provides complete configuration access and
displays settings, measurements, and calculated values. Easily set with
ACSELERATOR QuickSet

Product Summary
The SEL-2414 Transformer Monitor withstands harsh physical and electrical environments and is built and tested to
meet mission-critical IEEE and IEC protective relay standards. Apply the SEL-2414 to satisfy standalone or distributed
monitoring and control of transformers, or choose from the flexible communications options to connect to a substation
distributed SCADA or automation system, or a SCADA master. Communications options include serial, fiber-optic, and
Ethernet connections and ASCII, SEL Fast Message, M
IRRORED BITS
®
communications, Modbus, and DNP3 protocols.
Figure 1 shows the SEL-2414 functionality.
Apply flexible I/O options to meet the many needs of new or retrofit transformer installations. The SEL-2414 includes
four slots for plug-in I/O cards. Use digital inputs (DI) to monitor critical transformer alarms and status points. Use
analog inputs (AI) to measure pressure, oil level, temperatures, tap positions, and process-level signals (e.g., 4–20 mA,
0–1 mA) from transducers. Operate cooling fans, equipment, alarms, or provide indication with relay-contact or solid-
state digital outputs (DO) and analog outputs (AO). Measure ac currents and ac voltage to calculate three-phase power,
demand, energy, save in oscillographic reports, and for automatic control processes.
