MIL-STD-1399-300 Electric Power, Alternating CurrentThis military standard section establishes electrical interface characteristics for shipboard equipment utilizing AC electric power to ensure compatibility between user equipment and the electric power system. Characteristics of the electric power system are defined and tolerances are established, as well as requirements and test methods for ensuring compatibility of shipboard user equipment with the power system. The policies and procedures established by MIL-STD-1399 are mandatory. This section and the basic standard are to be viewed as an integral single document for use in the design and testing of electric power systems and user equipment.

b. For user equipment on the filtered, regulated AGD systems aboard SSN 774 Class ships, the user equipment should be tested for 3 minutes at the following voltages:

550 VDC on 440 Vrms AGD systems: 440 Vrms x 1.414 x 1.200 + 505 VDC = 1252 V

150 VDC on 115 Vrms AGD systems: 115 Vrms x 1.414 x 1.200 + 155 VDC = 350 V

Equipment and system manufacturers should be aware of the end use of their products to ensure that the design is capable of withstanding the AGD voltage levels associated with their end application.
