The IEEE Vehicular Technology Society (VTS) Philadelphia Chapter is holding a technical meeting.  The topic is AC Traction Power Protective Relaying Topics:  Schneider P-Series Protective Relays for AC Traction Power Systems.  Our speaker is Alexandre Piatniczka with Schneider Electric.

AC traction power substations along the Northeast Corridor and Philadelphia area were originally designed using single-function electromechanical and solid-state protective relays.  Railway agencies have recently been using multifunction digital relays when upgrading substations with new protection systems or when replacing existing relays at frequency converter stations.  The existing single-function protective relays can be adjusted using a screw driver and a 4-page manual.  The new multifunction relays can be programmed from a laptop while following a 450 to 1200-page manual, depending on the vendor.  Mr. Alexandre Piatniczka will present the Schneider P-Series multifunction digital relay and how it can be integrated into an existing traction power system, including recommendations on how to replace existing relay schemes.  Options to retrofit into the existing cutouts without needing to cut or replace the panel will be discussed.  A high-voltage breaker-and-a-half scheme will be used as an example. 

There is no charge for meeting attendance, only for PDH certificates.

Attendees may apply for 1.0 PDH provided through the IEEE Certificates Program, accepted in all states.  Member cost is $7.00 and non-member cost is $10.00 (USD) via vTools.  Credit card payments are processed through PayPal.  Checks will be accepted.   Complete online evaluation after lecture at https://r2.ieee.org/philadelphia-vts/forms/

Payment must be received and evaluation form must be completed within three days to receive PDH certificate.
