Mirrored Bits communications is an innovative, low-cost, relay-to-

relay communications technology that exchanges the status of eight

internal logic points called Mirrored Bits, encoded in a digital message,

between two devices. This patented technology opens the door to

numerous integration applications that would otherwise require more

expensive external communications equipment wired through contacts

and control inputs. Integration applications for Mirrored Bits commu-

nications include line protection pilot schemes, remote device controland monitoring, relay cross-tripping, and more.

Apply Mirrored Bits communications over radio channels for direc-

tional comparison protection schemes. This provides fast fault clearing

and preserves transient and voltage stability at very low cost. For

additional information on integrating your applications using

Mirrored Bits, visit www.selinc.com/mirroredbits .

In 1984, SEL invented the worlds rst digital distance

relay with a built-in fault locator, revolutionizing fault

nding. Current SEL event reporting technology and

software, such as the ACSELerAtor Analytic Assistant

SEL-5601 Software, makes wide-area monitoring,

collection, analysis, and control of power system datapossible.

Integrated systems with SEL synchrophasors take

event analysis one step further by providing the ability

to monitor power system distur-

bances in real time through angle

measurements, modal analysis, and

out-of-step detection. You can view

time-synchronized events together

using the SEL-5601 Software. SEL

uses the SEL-3378 Synchrophasor

Vector Processor (SVP) to createreal-time, wide-area monitoring,

protection, automation, and control

solutions.

The magnitude of the Northeast

power blackout on August 14, 2003,

could have been prevented, and

the data analyzed in minutes rather

than months, by using an SEL

integrated and synchronized event

monitoring and analysis solution.

Another outage in Florida on February 26, 2008, was

quickly analyzed by engineers using an SEL integrated

and synchronized solution. The engineers then used

their synchronized solution to improve their models

and prevent similar situations in the future. A NERC

press release on the Florida outage stated that synchro-phasors are like the MRI of the bulk power system.

Implement cybersecurity with substation-hardened

products from SEL. SEL relays and information

processors contain strong electronic access-control

technologies to effectively secure your cyberassets.

The SEL-3620 Ethernet Security Gateway secures

all Ethernet communications between your privatenetworks and interoperates with existing business IT

and control systems over an Internet Protocol Security

(IPsec) virtual private network (VPN). The SEL-3620

protects your private network from malicious trafc

with an integrated rewall and strong authentication

access control.

The SEL-3025 Serial Shield, an EIA-232, bump-in-

the-wire serial cryptographic transceiver, protects

meters, protective relays, programmable logic

controllers (PLCs), remote terminal units (RTUs),

and computers. The SEL-3025 prevents unauthorized

access, control, monitoring, and malicious attacks

by authenticating and optionally encrypting all data

along the communications path.

Our tough computers are also used in security solu-

tions for their inherent authentication, security

management, IPsec IP ltering, encryption, logging,

password protection, and authentication features.

Combine SEL technology with your policies, proce-

dures, and training for a complete solution. For more

SEL remedial action schemes (RAS) protect against

blackouts and system instability, increase corridor

capacity limits, increase reliability, respond automati-

cally to system contingencies, and bring your system

operation closer to its stability limits.

With remedial action schemes from SEL, you candetect and automatically respond to multiple,

consecutive system contingencies. Control thou-

sands of contingencies and loads with high-speed

MirroredBitscommunications or IEC 61850 GOOSE

messages. Preserve system stability using intelligent,

contingency-based actions, such as flexible load and

generation shedding. All loads and generation can be

prioritized and shed only when necessary to satisfy the

contingency. Remedial action schemes detect unstable

power conditions and automatically take corrective

action, such as system islanding, to avoid blackouts.Let SEL Engineering Services design a remedial action
