IEEE VTS Philadelphia Chapter Meeting

Transit signal use ungrounded energies to detect position of trains using vital circuit design.  The track circuit for this could be 300 feet to a few miles, so the exact position, direction, and speed of train is unknown.  This is an inefficient use of real estate especially, if 30 or more trains per hour have to operate.  To improve throughput, CBTC (communication based train controls) is being deployed, which also meets FTA/FRA PTC requirements.  However, CBTC uses 3 V or 12 V redundant design of computers and network switches which require Zero Reference Ground (ZRG).  How do you achieve ZRG in transit with leaking DC currents?

Attendees may apply for 2.0 PDH upon completion of lecture.
Certificates will be provided through the IEEE Certificates Program, accepted in all states.
