Abstract :
Amtrak is utilizing the electrification of the New Haven to Boston section at 25 kV, 60 Hz AC for all electric service between Washington DC and Boston. Efficient train operation requires uninterrupted availability of power supply to the trains. This, in turn, necessitates quick isolation of faulted section of overhead contact system and restoration of power in the healthy sections. An overview of the principles of automatic fault location and isolation system, which is installed, though not yet placed in service, to automatically isolate the faulted sections of overhead contact system with minimal time delay, is presented.
