2、cense from IHS-,-,-MIL-STD-1399-300B i FOREWORD 1. Preamble. This military standard is approved for use by the Department of the Navy and is available for use by all Departments and Agencies of the Department of Defense. 2. Purpose. This section defines the standard interface requirements for and th
3、e constraints on the design of shipboard user equipment that will utilize shipboard alternating current (AC) electric power. 3. Nature of the interface. In any system involving power source, distribution network, and load (user equipment), the characteristics at the system and user equipment interfa
4、ce are mutually dependent on the design and operation of both. In order for the electric power system to perform within the established tolerances, it is necessary to place constraints on the power source, the distribution system, and the user equipment. This interface standard defines the electric
5、power system characteristics. User equipment constraints are also established. 4. Structure. The technical content first delineates the characteristics of the shipboard electric power system at the interface in terms of voltage, frequency, continuity, and voltage waveform. Constraints on user equipm
6、ent design and installation, which are necessary to achieve shipboard compatibility with and to assure these characteristics, are then established. Finally, test requirements are specified to verify conformance of user equipment to this standard. 5. Invoking the standard. The Principal Development A
7、ctivity (PDA) will consider the mission requirement of the user equipment being developed or acquisitioned. The PDA will then select those conditions under which the user equipment is to operate and those conditions, which the user equipment will withstand without failure, but not necessarily, opera
8、te normally. The PDA will also specify those tests commensurate with the equipments mission, which will ensure the user equipments satisfactory operation, the user equipments compatibility with the shipboard electric power system and other equipment, and the equipments survival. 6. NATO coordination
9、 and standardization. The standard characteristics of AC electric power supplied for U.S. Navy ships have been coordinated with NATO standardization documentation, where applicable. In particular, the standard characteristics of Type I and Type II power conform to corresponding power types specified
10、 in STANAG 1008 (Edition Number 8). 7. Numerical quantities. Numerical quantities are expressed in metric (SI) units. 8. Contact information.

This military standard section establishes electrical interface characteristics for shipboard equipment utilizing AC electric power to ensure compatibility between user equipment and the electric power sy
45、stem. 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 an
46、d 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. 1.2 Classification. Types of shipboard electric power to be supplied from the electric power system are classified as low voltage as follows: Type I -
47、Type I power is 440 or 115 volts (V), 60 hertz (Hz) ungrounded and is the standard shipboard electric power source. Type I power is used unless a deviation is granted (see 4.4) Type II - Type II power is 440 or 115 V, 400 Hz ungrounded and has only limited application. Use of Type II power requires
48、the submittal and approval of a deviation request (see 4.4). Type III - Type III power is 440 or 115 V, 400 Hz ungrounded having tighter tolerances as compared to Type II. Type III power has restricted use and its use requires the submittal and approval of a deviation request (see 4.4). 1.2.1 Specia
49、l power classification for avionic shops and aircraft servicing. Types of shipboard electric power supplied only for avionic shops and aircraft servicing are as follows: Type I - Type I power is 115/200 V, 60 Hz, 3-phase, 4-wire, wye-grounded. This power is only provided for avionic shops. Type III - Type III power is 115/200 V, 4
