- Simple
and Economical Line Protection
Two forward-looking zones of phase and ground mho distance elements for simple
and economical distance protection. Phase and ground inverse-time and definite-time
overcurrent elements provide backup protection.
- Innovative
Logic for Secure and Stable Operation
Innovative logic detects CCVT transients and prevents Zone 1 overreach on
high SIR applications. Positive-sequence memory voltage polarization provides
dependable, secure operation for close-in faults by expanding the mho operating
characteristics in proportion to the source impedance. Best Choice Ground
Directional Element™ logic for adaptive ground fault directional polarization.
- Synchrophasor Measurements
Turn state estimation into state measurement with wide-area measurement of voltage and current phase angles and magnitudes. Improve system stability with high-speed, load-angle measurements. Increase stable loading with analysis of voltage and angular stability.
- Monitoring
and Metering
Event reports, Sequential Events Recorder (SER), circuit breaker contact
wear monitor, substation battery monitor, and instantaneous and demand metering.
- Communications
EIA-232 and EIA-485 serial ports for local/remote access and system integration. MIRRORED BITS® communications
for eight channels of secure relay-to-relay logic communications available
on both rear-panel EIA-232 serial ports.
- Advanced
Protection and Control Logic
SELOGIC® control equations
with 16 SELOGIC variables, 16 timers, 16 latch
bits, and 16 remote control elements for customizing advanced protection
and control schemes. Sixteen local control elements and 16 programmable display
points with optional front-panel LCD and operator pushbuttons.

- Implement wire-alike
and application setting upgrades for popular SEL-2PG10 distance
relay applications.
- Use step distance
protection for primary and backup three-pole tripping on non-series-compensated
transmission and subtransmission lines.
 Send synchrophasor data to SCADA and wide-area measurement systems using SEL Fast Messages at rates of up to 60 times per minute. Accuracy of ± 1 degree and microsecond timing of event reports improve system visualization and event analysis. Use SEL-5077 SYNCHROWAVE® Server Software to time-correlate synchrophasor data from SEL-311 Relays and send it to display and archiving systems, such as SEL-5078 SYNCHROWAVE Console Software- Use accurate
fault locator to efficiently dispatch line inspection and repair
personnel.
- Program breaker
failure logic with SELOGIC® control
equations.
- Back up transformer
and generator protection with zone distance and overcurrent elements.
- Schedule as-needed
circuit breaker maintenance, and send alarms when the breaker wear
monitor detects excess breaker contact wear from the number of
operations and magnitude of interrupted current.
- Alarm for low
voltage conditions on station battery.
- Use SEL-5040
Power System Report Manager Software to automatically gather
relay event reports on your PC and manage them with a database.
- Use SEL-5010
Relay Assistant Software to manage your relay settings.
- Use SEL-5601
Analytic Assistant Software to display oscillograms and vector
diagrams to analyze event reports.
