The 2nd phase of R&D project Noise under Federal Target Program «Development of Civil Marine Technologies».
Under this phase KRSC has completed the basic design of type systems for cancelling ELFE and normalizing the permanent magnetic field in ships and other marine platforms to meet permissible levels required by the Sanitary Code.
The strongest ELFE sources in ships are components of ship’s electric grid: cables, boards and powerful distribution and switching gears. The level of electromagnetic emissions generated by such devices is governed by current amplitudes in electric circuits, while the absorbed currents are defined by the load changing during ship operation.
ELFE levels are efficiently reduced using automatic cancelling technique. Experimental studies on a breadboard model of such system confirmed its advanced capabilities. Presently, a test prototype of the system is being manufactured.
The permanent magnetic field in the compartments of ships and other marine platforms needs to be normalized because its levels are lower than the natural level of the Earth’s magnetic field, which may have detrimental effect on crew performance and health. Weakening of the permanent magnetic field depends on the specific location of ship’s compartment, structural materials as well as geographical location of the ship herself.
The system designed for normalizing the permanent magnetic field in ship compartments to reach the levels prescribed by relevant regulations is using an assembly of circuits arranged around the «ceiling» and «floor» perimeter to generate a sufficiently uniform field within the given compartment so that its level is close to the Earth’s magnetic field.
A stable current source has been developed for the electric circuits with low current ripple and adjustable settings. The magnetic field density is monitored using a
