IEEE VTS Philadelphia Chapter

The IEEE Vehicular Technology Society (VTS) Philadelphia Chapter is holding a virtual meeting using Zoom. The topic is Transit Traction Power Cables: Replacement Guidelines. Dr. Kasim Korkmaz, Associate Professor in Civil Engineering and Construction Management at Eastern Michigan University, is our guest speaker. The transit industry uses insulated cable for traction power supply and negative return cables between traction power substations, tie switches, and points of delivery to the vehicles. Third rail systems use jumper cables to provide continuity of power around third rail gaps and expansion joints. The conductor insulation system used for traction power cables, as well as for lower voltage power distribution and signal/communication systems, typically has a specified life of 30 years. Many of the transit systems in the United States are that age or older with original cables still in service. Many cables within transit tunnels have had failures because of the water penetration through and around the cable insulation, causing damage to the insulation and corrosion of the copper conductor. In some subway tunnels, the conduits themselves have degraded to the point where they cannot be cleaned out and reused for their original purpose. Transit systems have experienced cable fires and system-wide closures due to the degradation of traction power cable insulation. In recent years, major storms affecting the United States have inundated transit tunnels with fresh and contaminated water and exacerbated cable lifecycle concerns. Dr. Korkmaz will discuss the causes of cable damage and the replacement criteria for traction power cables. Attendees may apply for 2.0 PDH upon completion of webinar. Please include your email address when registering to receive an evaluation form required for PDHs. PDHs are paid by using Zelle or mailing a check to Brandon Swartley. Instructions to be given during meeting. Certificates will be provided through the IEEE Certificates Program, accepted in all states.
