Abstract:   The SEPTA Wayne Junction Static Frequency Converter (SFC) Station converts 60 Hz, 3-phase utility power to 25 Hz, 1-phase traction power for SEPTA’s 12 kV, 25 Hz regional rail system.  SEPTA is replacing the Westinghouse LCB II line differential and GE CEY line distance relays, including the existing audio tone and transfer trips systems, that protect PECO 230 kV lines 220-28 and 220-42 supplying the SFC station.  The replacement relays are SEL-411L and SEL-311L line differential relays, serving as primary and backup schemes using fiber optics to communicate with adjacent substation relays.  This presentation introduces the multifunctional SEL-411L and SEL-311L line current differential relays.  Line current differential theory is discussed as well as the operating principles of both relays, how they are similar, and where they differ.  Hardware, logic, settings, and example applications are presented.


Speaker:  Frank J. Heleniak earned his B.S. in electrical engineering and B.S. in physics from Widener University in 2014 and M.S. in electrical engineering from Villanova University in 2018.  Frank joined Schweitzer Engineering Laboratories, Inc. in 2014 as an associate application protection engineer and is currently a regional technical manager.  His responsibilities include protective relaying application support and technical training.  Frank is a registered professional engineer in the state of Pennsylvania and a member of IEEE.
