DESCRIPTION:Transit signal use ungrounded energies to detect position of tr
 ains using vital circuit design. The track circuit for this could be 300 f
 eet to a few miles\, so the exact position\, direction\, and speed of trai
 n 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 (co
 mmunication 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?\n\nAttendees 
 may apply for 2.0 PDH upon completion of lecture.\nCertificates will be pr
 ovided through the IEEE Certificates Program\, accepted in all states.\n\n
