CRITICAL RELAY STUDY FOR NS SAVANNAH APPLICATIONS

This study resulted from isolated incidents involving electrical relays that have occurred throughout the period of the N.S. Savannah operation. The various incidents were caused by equipment that failed to operate properly or came into operation without fulfillment of all normal conditions for operation. This report covers: (1) general considerations requiring attention in selecting relays; (2) a list of relays in the Savannah's instrumentation and a summary of the types used; and (3) analysis of specific problems in which relays are the suspected source of trouble, and presentation of recommendations for correcting such problems.
