IEEE VTS Philadelphia Chapter Meeting

A 230 kV substation is undergoing a relay replacement project.  Westinghouse LCB II line differential and GE CEY line distance relays, including existing audio tone and transfer trip systems, presently protect 230 kV incoming transmission lines.  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.

Attendees may apply for 1.0 PDH upon completion of lecture for a cost of $9.00.
Certificates will be provided through the IEEE Certificates Program, accepted in all states.

Lunch will be provided complementary.
