Product
Current Differential Relay
SEL-587
-
Schweitzer Engineering Laboratories, Inc.
The SEL-587 Current Differential/Overcurrent Relay provides protection for any two-input apparatus, such as transformers, motors, generators, and reactors. Apply it for differential and overcurrent protection and use event reports for quick post-event analysis.

Product
Arc-Flash Protection
-
Schweitzer Engineering Laboratories, Inc.
Arc-flash detection technology significantly decreases the time it takes a relay to trip in response to an arc fault, thereby reducing hazardous incident energy. Combining light-sensing technology with fast overcurrent protection provides high-speed arc-flash detection and prevents overtripping for external faults. Arc-flash protection relays work with low- and medium-voltage apparatus and easily coordinate with other devices in utility-, industrial-, and commercial-scale power systems.

Product
Distributed I/O
-
Schweitzer Engineering Laboratories, Inc.
Expand the I/O of SEL relays and communications processors, reduce copper in substations by transferring I/O from remote locations over fiber, and provide electrical isolation to avoid ground paths and induced noise and interference.
