SEL Solutions for Wind Energy
Wind Generator Feeder Protection
The SEL-700GW provides complete dual feeder protection for distributed generation. High system availability is
obtained by using two sets of overcurrent elements (50/51) to detect and isolate a fault on either feeder. The
SEL-700GW also provides many functions of a programmable logic controller (PLC). Multiple communications options,
a variety of I/O choices, and programmable SELogic® control equations make the SEL-700GW a complete solution.

Protection Relay
Grid Interconnection
The SEL-700GT provides an IEEE 1547-compliant intertie protection solution
for distributed generation. Optional synchronous generator protection and
synchronization provide complete generator and intertie protection in one
compact and economical package. Multiple communications options, various
I/O choices, and programmable SELogic control equations make the SEL-700GT
a complete solution for intertie and generator protection.

Fault Indication
SEL Faulted Circuit Indicators (FCIs) help operations personnel quickly determine the fault
location, isolate the faulted section, and restore power. As depicted in the illustration below, the
terminations used for underground cables in the transformers and junction boxes are excellent
locations to install faulted circuit indicators. Features and benefits include:
• Line-powered operation (no batteries required) means longer life and limited maintenance.
• High 1200 A current trip value with delayed trip response time option coordinates with most
systems.
• Remote display allows indicator status to be quickly determined without opening the enclosures.
• Easy installation on terminators with capacitive test points saves time.
• Integrated junction shields ensure adjacent phase immunity in junction box applications.
• Applicability in both transformers and junction boxes reduces installation errors.

Distributed Generation Interconnection
The SEL-547 Distributed Generator Interconnection Relay allows a wind turbine to be connected to
the electric utility grid. When the SEL-547 detects a condition that could adversely affect the
generator or the electric grid, it sends a trip signal to the breaker, separating the wind turbine
from the utility supply.
SEL-547 Distributed
Generator Interconnection Relay
• Low-cost compact package incorporating essential
protection and control elements for distributed generation
• Protection and control elements required by IEEE 1547
• Modbus® and SEL communications interface
Revenue and Power Quality Metering
The SEL flagship SEL-734 and SEL-734P Advanced Metering Systems provide high-accuracy, fourquadrant metering with advanced load profile recording. In addition to revenue metering, the
SEL-734P meter provides advanced yet user-friendly power quality reports, capacitor bank control,
and time-synchronized phasor measurements. Indoor mounting options and prewired outdoor
enclosures from SEL facilitate high-end metering at virtually any location.

Feeder Protection
SEL-751A Feeder Protection Relay
With Arc-Flash Detection
SEL feeder protection solutions provide complete feeder protection, with overcurrent, overvoltage,
undervoltage, and frequency elements with flexible I/O options, easy mounting, and fast settings.
With the SEL-751A Feeder Protection Relay, you can easily upgrade protection without cutting or
drilling existing cutouts with a small form factor and multiple mounting adapters. Quickly integrate
into serial- or Ethernet-based communications with IEC 61850, Mirrored Bits®, DeviceNet™, and other
protocols. The SEL-751A also provides fully automatic protection against dangerous arc-flash events.
Without arc-flash detection (AFD), an arc flash can cause severe personal injury, extensive equipment damage, and lengthy system outages. AFD interrupts power to the arc flash before it can
cause significant damage.
Transformer Protection
SEL-787 Transformer Protection Relay
SEL transformer protection solutions allow you to optimize the life of your transformers by monitoring key health indicators with cumulative through-fault current recording measurement and logic
input. With the SEL-787 Transformer Protection Relay, you can apply 2 three-phase winding inputs,
and an optional single-phase restricted earth fault input and three-phase voltage input. Benefits
include advanced automation and flexibility, single or dual, copper or fiber Ethernet communications ports, asset management data, and easy retrofit of most electromechanical relays.
Alarm and Annunciation
Make complex alarming simple with SEL’s alarm and annunciation panels, including 42 inputs, 11
outputs, programmable logic, and up to four communications ports supporting DNP3, Modbus, and
SEL protocols. You can simplify commissioning and troubleshooting with a built-in sequence of
events recorder and full software HMI. Apply an SEL-3010 Event Messenger for telephone voice callout of critical alarm conditions.

Breaker Failure Protection and Control
SEL solutions provide breaker failure protection, breaker control, and breaker monitoring. Benefits
of the SEL-352 Breaker Failure Relay include a cost-saving data recorder and a sophisticated
controller to reduce maintenance and manual operations. The relay features circuit breaker failure
protection, including failure to trip for fault or load conditions; failure to close, including pole
disagreement; failure while open (flashover detection); failure to complete a trip or close due to
stuck resistor switches; and loss of dielectric pressure.
SEL-352 Breaker Failure Relay
Line Protection
With SEL, you can protect any transmission line using a combination of five zones of phase- and
ground-distance and directional overcurrent elements. A graphical user interface system provides
logic and application templates for typical line protection schemes while patented coupling
capacitance voltage transformer (CVT) transient overreach logic enhances the security of Zone 1
distance elements. Best Choice Ground Directional Element® logic optimizes directional element
performance and eliminates many directional settings. Apply the SEL-421 Protection, Automation,
and Control System for high-speed distance and directional protection and complete control of a
two-breaker bay. Use synchronized phasor measurements (synchrophasors) from SEL relays and
meters to detect and correct islanding, interarea oscillations, and other dynamic system conditions.
SEL-421 Protection, Automation,
and Control System
Capacitor Control
Simplify relay settings, application, and inventory by using one relay for all of your capacitor bank
needs. The versatile SEL-487V Capacitor Protection and Control System can handle grounded and
ungrounded, single and double-wye capacitor bank applications. It provides sensitive voltage differential and current unbalance protection with compensation adjustment for small voltage differential
levels due to variations in individual capacitor elements from manufacturing, potential transformer,
or instrument transformer measurement error. Each differential and unbalance element provides
three levels of detection, low set alarm level, trip pickup level, and high-level trip pickup level, each
with its own definite time delay. Instantaneous- and time-overcurrent elements, as well as voltage
elements, provide backup protection.
Information Processors
SEL information processors integrate power protection, automation, control, and monitoring
by communicating with a variety of microprocessor-based devices. With the SEL-3530 RealTime Automation Controller (RTAC), you can integrate station control, reporting, and logging
through one reliable system. acSELerator RTAC™ Software simplifies the design of integration and
automation while the embedded RTAC web interface speeds setup and monitoring of critical data
on network access, user accounts, and system performance.

and other high-accuracy timing needs. The SEL-2407® Satellite-Synchronized Clock provides six
demodulated IRIG-B time-code outputs with three user-selectable outputs for 1 PPS or 1 kPPS output.
