What is one major advantage of a diesel-electric propulsion plant -
ANSWER excellent manoeuvrability
Which of the following is a disadvantage of electric drive propulsion
systems - ANSWER Propulsion motors are required along with
electrical power generation machinery.
Which statement is TRUE concerning electric propulsion drives -
ANSWER The propeller speed and direction of rotation are easily
controllable.
An electric propulsion drive system in which the propulsion generator
supplies power to both the propulsion motor and ship service loads is
referred to as what type of system - ANSWER an integrated system
Which of the listed temperature measuring devices installed on a large
turbo-electric alternating current propulsion generator would be the most
reliable for monitoring generator temperatures to avoid premature
winding insulation failure - ANSWER Temperature sensors inserted in
the stator slots for measuring stator winding temperature.
