High Voltage On Board Ship

The main bus bar.

High voltage on board ship. Typical marine hv systems operate usually at 3 3kv or 6 6kv. It is usually a 3phase 60hz 440 volts supply being generated and distributed on board. Normally low voltage system is common on board. Typical marine hv systems operate usually at 3 3kv or 6 6kv.

As the ship size increases there is a need to install more. Typical marine high voltage system voltages are 3 3 kv 6 6 kv and 11kv. The numerical definition of high voltage depends on context. Any voltage used on board a ship if less than 1kv 1000 v then it is called as lv low voltage system and any voltage above 1kv is termed as high voltage.

Sriram balasubramanian 21 827 views. Hanif dewan chief engineer and maritime lecturer trainer bangladesh. Onboard a merchant ship the supply is usually 440 volts 60 hertz however higher voltages of 6 6kv are possible on lng tankers special purpose ships and passenger vessels having electrical propulsion. High voltage in ships we all know about the voltages used on board a ship.

Any voltage used on board a ship if less than 1kv 1000 v then it is called as lv low voltage system and any voltage above 1kv is termed as high voltage. The major differences between high voltage supply and low voltage supply on board ships are. The main bus bar can be found inside the main switch board. Safeties applications of high voltage in ships mohd.

Why high voltage system used on ships in ships voltages upto and equal to 1000 volts is called as low voltage system and voltages above 1000 volts is called high voltage system. High voltage system on ships. In ships voltages upto and equal to 1000 volts is called as low voltage system and voltages above 1000 volts is called high voltage system. Isolated equipment must be earthed down 3.

High voltage in ships we all know about the voltages used on board a ship. High voltage systems are more extensive with complex networks and connections 2. Passenger liners like qe2 operate at 10kv. It is usually a 3phase 60hz 440 volts supply being generated and distributed on board.

But rising demand for power due to heavy consumers on new ships require an efficient and surplus power supply. Normally low voltage system is common on board. Skip navigation sign in. Why high voltage is used on board ships.
