SEL-387 -
Schweitzer Engineering Laboratories, Inc.
Protect and control any two-, three-, or four-winding power transformer with the SEL-387, which provides thermal and through-fault monitoring, and with SELogic Control Equations, can detect breaker failure.
-
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.
-
