Ship Electrical Distribution Systems and Protection

These flashcards cover key concepts and terminology related to ship electrical distribution systems and protection mechanisms.

Electrical Distribution System

A system onboard a ship that controls the flow of current by opening and closing circuits, incorporating protection devices against overloads and faults.

Switchboard

A collection of panels that control a generator and distribute power to each load on a ship.

Generator Synchronization Panel

Panel on the switchboard that facilitates the coordination of multiple generators to ensure balanced power distribution.

Overload Protection

Devices incorporated into electrical distribution systems to prevent circuit burnout and fire hazards due to excessive current.

Radial Distribution Scheme

A power distribution arrangement where loads are connected in a radial configuration from a central point.

Zonal Distribution System

A power distribution scheme that organizes loads into distinct zones fed from main switchboards for improved efficiency.

Bus Feeder

Conductors that connect the main switchboard to various loads, serving as a pathway for electrical energy.

Main Switchboard

The primary electrical panel onboard a ship, where main power distribution occurs and where various electrical systems are managed.

Local Switchboard

Secondary switchboards located in different areas of the ship that control local distributions of power.

Circuit Breaker

A protective device used to interrupt current flow in a circuit when an overload or fault is detected.
