Abstract

A modern vessel is a complex system that includes many technical means with different functions and operating principles. Electromagnetic interference occurs in electrical power systems, which can cause electrical equipment failures. Ships are characterized by close proximity of highly sensitive equipment, power equipment and cable routes, which are subject to interference. Ensuring electromagnetic compatibility is complicated by the growth of energy saturation of ships, the widespread use of digital technology in control systems and information processing. The paper demonstrates the results of electrostatic discharge for ship cable with the amplitude of 25 kV. The interference is simulated by the simulator ESR-25000 for a braided cable and a metal tube that simulates metal structures on the ship. ESR in the screen of the ship cable leads to the propagation of pulse voltage across the screen and the appearance of voltage on the internal veins. Attenuation of interference at the far end of the cable after 50 meters is not more than 10 % of the original voltage pulse.
