2. Arc-Flash Mitigation – Provide arc-flash detection capabilities.
3. Event Analysis – Conduct post-event analysis with detailed event records that combine oscillographic and digital information.

SEL-700G:

1. Generator Protection – Provide generation protection with current, voltage, frequency, distance, power, and out-of-step elements.
2. Current Differential Protection - Protect equipment using using sensitive percentage-restrained current differential elements and an unrestrained element, along with synchronism check and volts-per-hertz elements. 
3. Islanding Protection - Detect islanding conditions using vector shift function.

SEL-587Z:

1. Bus Differential Protection – Protect equipment using high-impedance differential elements for fast tripping for in-zone faults.
2. Transformer Differential Protection – Protect transformers using high-impedance differential elements for fast tripping for in-zone faults.
3. Reporting and Monitoring – Provide sequential recorder to document events such as faults, trips, voltage, and current.

SEL-735:

1. Revenue Metering – Track energy usage in compliance with ANSI/IEC accuracy class requirements.
2. Load Profile Data Collection – Collect and store billing data with load profile recorder.

SEL-3530/3555:

1. Multiple Device Functions - Capable of using as a protocol gateway, RTU, logic processor, PAC, engineering port server, event processor, and system-wide SER logger/viewer.
2. Rugged Hardware – The controller shall be designed and tested to meet or exceed IEEE 1613 and protective relay specifications for harsh environments and to withstand vibration, electrical surges, fast transients, and extreme temperatures.
3. Seamless Configuration – Design an integrated automation system that includes protocol conversion, SCADA communications, IEC 61850 integration, synchrophasors, time synchronization, data management, and programmable logic.

SEL-3355

1. Industrial Automation Platform - Deploy automation control and operator station functionality in a single package directly to the plant floor without the concern of environmental conditions. Support soft programmable logic controllers (PLCs) and operator HMI control engines.
2. HMI Visualization, Monitoring, and Control – Provide system visualization, monitoring, and control point.
3. Information Processor – Collect and format relay data for legacy remote terminal units (RTUs), and send the data directly to SCADA systems using legacy protocols.

SEL-2440

1. Substation Automation - Provide fast I/O, programmable logic, flexible communications, and SCADA integration
2. I/O Annunciation - Indicate I/O status for each input and output. Simplify commissioning and troubleshooting with device status and port activity indicators.
3. System Automation - Communicate with DNP3, Modbus, LAN/WAN, IEC 61850, and other protocols over Ethernet and serial connections.

Following protocols for all SELs include the following:

• Modbus RTU
• SEL ASCII and Compressed ASCII
• SEL Fast Meter, Fast Operate and Fast SER
• SEL Fast Messaging
• SEL Mirrored Bits Communications
• Event Messenger
