DDG 51 class Naval Ships had been plagued with frequent uncommanded cyclings of fire main valve controllers during automatic bus transfers (ABTs) of 440 Vrms power. The fire main valve controller is one of approximately 90 critical resource controllers aboard ship. Data was acquired aboard ship, analyzed and empirically reproduced at a test facility. A general solution was hypothesized during this testing and subsequently optimized using transient and circuit modeling. The solution has been implemented as a shipset aboard DDG 72 since September 1998 with no reoccurrence of uncommanded cyclings due to ABTs; implementation is planned on all applicable DDG 51 class ships
