The MIL-STD 1399-300B electric power, alternating current standard, developed by the U.S. Department of Defense, describes the electrical interface specifications for shipboard equipment that uses alternating current electric power to ensure compatibility between user equipment and the electric power system.
This standard defines the characteristics of the electrical power system and establishes tolerances. It also provides requirements and test methods to ensure compatibility of onboard user equipment with the power system.
Policies and procedures in the MIL-STD-1399 standard are mandatory. This standard is recognized as a single integrated standard for use in the design and testing of electrical power systems and user equipment.
The widespread use of power electronics on ships and offshore installations, especially in electric propulsion vessels, has a significant impact on the power quality of the power distribution system. The effects of harmonic distortion generated by commercial uninterruptible power supplies, especially used in naval ship applications, are much discussed.
The MIL STD 1399 300B standard defines electrical interface power requirements for ship and submarine equipment. The current waveform test required by this standard provides current harmonic control limits for single-phase and three-phase equipment operating at 60 Hz and 400 Hz services.
The measurement and control of current harmonics, especially power electronics equipment, is considered essential for defense platforms both on land and on land. It is also within the scope of electromagnetic interference control for subsystems and equipment requirements provided by the test method presented in the MIL STD 461 standard.
In many cases, measurement techniques and limits are used and shared between the two standards. However, if one method is used against the other, it creates differences that cause errors in compliance reporting. In general, the requirements of current waveform testing performed in accordance with the MIL STD 1399-300B standard are compared with the requirements of testing performed under the MIL STD 461 standard.
Briefly, this military standard specifies electrical interface specifications, defines electrical power system characteristics, and establishes tolerances for ship equipment that uses alternating current electrical power to ensure compatibility between user equipment and electrical power system.
