What type of transformer systems are utilized to keep shore power sources isolated from onboard sources?

Polarization transformers are specifically designed to keep shore power sources isolated from onboard systems, aiding in safety and preventing possible electrical faults. By ensuring that the electrical connection from shore power is isolated, polarization transformers help to avoid ground loop issues and protect onboard equipment from interference or damage that could arise from improper grounding or connections.

In marine applications, this isolation is crucial as it enhances safety for both the vessel and the individuals operating it, while also maintaining the integrity of the vessel’s electrical system. This is in contrast to other types of transformers, such as step-up or step-down transformers, which are designed primarily to modify voltage levels rather than to provide this critical isolation function.
