Apply low-cost, compact package with essential protection and control elements for distributed generation.
- SEL-587 Current Differential Relay
Apply economical differential protection for two-winding transformers or any two-terminal apparatus.
- SEL-387 Current Differential and Overcurrent Relay
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-2600 RTD Module
Measure and transmit data from up to 12 RTDs and a single contact status located in transformers, breakers, motors, generators, or other system apparatus.
SEL University - Generation System Protection (PROT 409)
This generator protection course provides an in-depth study of the methods used in designing complete protection for generation systems. Course participants will study and discuss generator protection methods and relay setting calculation. At the conclusion of this course, students will be able to apply generator protection principles and calculate critical generator protection elements for system implementation.
