SEL-2414 Transformer Monitor
Complete System for Control and Monitoring

Major Features and Benefits

The SEL-2414 Transformer Monitor provides an exceptional combination of monitoring, control, and communications
in a compact package.
Thermal Monitoring and Metering Capabilities. Safeguard transformers from overheating by tracking thermal
conditions. Track the minimum and maximum transformer top oil temperature, hot-spot temperature, and as many
as 10 RTDs or thermocouples. Calculate hot-spot temperature according to the IEEE C57.91-2011 or the
IEC 60076-7:2018 Ed. 2 standards.
Load Tap Position And Control Monitoring. Monitor tap position and raise and lower controls and as many as
32 tap positions by using digital inputs in the binary-coded decimal (BCD) or binary format.
High Reliability, Rugged Design, and Low Price. Apply the SEL-2414 in harsh physical and electrical environ-
ments. The SEL-2414 withstands vibration, electrical surges, fast transients, extreme operating temperatures from
–40° to +85°C, and meets stringent utility standards. Compare our superior specification compliance, higher reli-
ability, lower price, and worldwide, ten-year warranty to other transformer monitor alternatives.
Flexible I/O for Transformer Status, Alarms, and More. Take advantage of input/output options including dig-
ital inputs for status such as oil level and sudden pressure; RTD and thermocouple inputs for measurements such 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 mon-
itor applications. Monitor critical substation assets with comprehensive transformer thermal and through-fault
monitoring.
