Industry Focus: Maritime Applications

For maritime shipping, a reliable power supply for on-board networks and drives for man and machine is indispensable for safe navigation on the world’s oceans. Ship generators produce the necessary energy, which is fed into the on-board network via medium-voltage (MV) transformers.

In order to avoid an overload of generator and MV transformer during switch-on processes, the special TRAMAG Premagnetizing Transformer is connected in series with the MV transformer on the secondary side in order to charge it. This premagnetization process prevents an uncontrolled increase of the inrush current, which would damage the generator and MV transformer and thus block the power supply.
