Investigations of radioelectric disturbances produced by thyristor control-and-regulation of voltage systems on sea-going ships

In the planning of a ship it is necessary to provide security for the electric network against radioelectric disturbances noise and especially of a ship with a combustion-prime prime mover supplied with thyristor subsystems for regulation and control. The simplest and most economical currently is the securing of the feed cables that feed the radio cabin the navigation one, the hydroacoustic one and the computing center with anti-noise filters of an attenuation of 100 db, installed on the outside wall of the cabin in the place of input of the cable into the cabin. On research ships it is necessary to use individual separated galvanized electrical circuits networks that supply the electronic radio, navigational, hydroacoustic, and calculating system, in order to insure them against disturbances proceeding from thyristor subsystems for regulation and control.
