Transformer Monitor

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. Choose I/O options that fit your unique needs, from detecting oil levels and sudden pressure to alerting alarm systems or control functions. As always, the SEL-2414 is protected by SEL's no-questions-asked, worldwide, ten-year product warranty.

Monitor Transformer Life—Track transformer loss-of-life using the IEEE C57.91-1995 thermal model for various winding configurations (including three sets of single-phase transformers). Directly measure ambient and top oil temperatures with a resistance temperature detector (RTD) or thermocouple (TC) input card. Monitor both digital and analog sensor outputs, such as oil level and pressure.

Increase System Awareness—In addition to basic metering, such as voltage and current measurements, the SEL-2414 also provides metrics, such as maximum/minimum metering, demand and peak demand values, and energy data. Thermal model reports allow you to accurately trend the transformer’s load and correlate the data with other system parameters. Use the meter data to better manage your assets and plan for future expansion.

Manage and Protect Critical Assets—Manage and protect critical substation assets with comprehensive transformer thermal and through-fault monitoring. Assert alarms based on the thermal condition of the transformer or on other monitored conditions.

Transformer and Fan Control—Control load tap changers (LTCs) in a wide variety of applications, from distribution transformers to large autotransformers (refer to product literature for implementation). In addition, exercise transformer cooling fans to eliminate maintenance surprises during critical load conditions. Separately control fan banks to balance cooling duty cycles and increase the life of cooling systems. Implement LTC and fan control with the design templates in acSELerator QuickSet SEL-5030 Software.


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.

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.

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; 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.

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. Send the SER data to a communications processor or computer for system analysis.

Communications and Integration
Automate fan bank control with flexible communications options that provide easy integration with SCADA. Choose from Ethernet, Modbus TCP, DNP3 LAN/WAN, IEC 61850 , Telnet, FTP, Modbus Serial, EIA-232, EIA-485, and DNP3 RTU protocols.

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.

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.
