What does it means “reverse power ?
Reverse power is condition reverse which power flows from the bus bar into the generator. This condition can occur
when there is a failure in the prime mover such as an engine or a turbine which drives the generator.
Causes of Reverse Power
The failure can be caused to a starvation of fuel in the prime mover, a problem with the speed controller or
an other breakdown. When the prime mover of a generator running in a synchronized condition fails. There
is a condition known as motoring, where the generator draws power from thebus bar, runs as a motor and
drives the prime mover. This happens as in a synchronized condition all the generators will have the same
frequency. Any drop in frequency in one generator will cause the other power sources to pump power into
the generator. The flow of power in the reverse direction is known as the reverse power relay.
Another cause of reverse power can occur during synchronization. If the frequency of the machine to be
synchronized is slightly lesser than the bus bar frequency and the breaker is closed, power will flow from the
bus bar to the machine. Hence, during synchronization(forward), frequency of the incoming machine is kept
slight higher than that of the bus bar i.e. the synchroscope is made to rotate in the “Too fast” direction. This
ensures that the machine takes on load as soon as the breaker is closed.
- What does it mean low insulation?
Low insulation is the situation when the insulation is low due to bad wiring or have some shock wire to the ground or
earth. - How to trace to identify the low insulation?

Discharge of sewage using sewage treatment plan at distance more than 4 nautical mile from nearest land.
Or sewage which is without treat at a distance more than 12 nautical mile from nearest land.
The discharge of sewage from holding tank should not instantly but moderate rate when ship is proceeding at not less
than 4 knot. - What is principles using sewage treatment plan?
Sewage on sea is generally the waste produce from toilet, urinals and WC scuppers.
In the sewage treatment plan, the sewage is collect and treat by decomposition of the raw sewage by aerobic
bacteria. - What are three chamber inside the sewage treatment plan?
- Aerating Chamber
This chamber is fed by row sewage which has been grinded to from small particles. The advantages of
breaking sewage in small particles is that increase the area and high number of bacteria can attack
simultaneously to decomposed sewage. The bacteria can survive by the air flow through diffuser
into the air chamber. The air produces and forced by air compressor.
- Chlorination Chamber
In this chamber the clear liquid produce from settling in overflown after mixture of liquid passed to settling
tank and the sludge settles at the bottom and clear liquid on the top.
The liquid is disinfected with help chlorine, and reduce the bacteria present in the liquid by chlorination. - Clear liquid chamber
The clear liquid or after disinfected collected in this chamber to ready for discharge to the sea. - How do you flush sewage treatment?

the parameter of engine while running. - What is the use air intake shutter valve?
The intake shutter valve is also called throttle valve. There is valve to stop the air supple to the combustion room in
the cylinder.
Some diesel engines use an intake shutter. The intake shutter has following functions.
(1) Stops vibration immediately after engine is turned off. In diesel engines, air continues to be drawn into the cylinder
and compressed even after the ignition switch is turned off. To prevent vibration from occurring immediately
after engine is turned off, the intake shutter is closed immediately after the ignition switch is turned off in
order to shut the intake air off and stop the engine smoothly.
(2) Reduces intake air noise. During deceleration, or low speed and light load, the amount of the intake air is reduced
by the intake shutter. The intake air noise is reduced without drawing unnecessary air into the intake
manifold. - What is the function of expansion valve and solenoid valve in AC plan?
Expansion valve:
Is component in refrigerant and air conditioning system that control the amount of refrigerant flow into the evaporator
thereby controlling the superheating at the outlet of the evaporator.
Solenoid valve;
Is an electromechanically operated valve. The valve is controlled by an electric current through a solenoid, in the case
of two-port valve the flow is switch on or off. In the case a three-port valve, the outflow is switched between
the two outlet port. - What does its mean power factor on electric power station?
Power factor
Power factor as the Cos φ in the triangle
In electrical engineering, the power factor (PF or cosφ) is
the ratio between the power than can be used
in electric circuit (real power, P) and the power from the
result of multiplication between
the current and voltage circuit (apparent power, S). The power factor is defined as
PF ranges from zero to one. The higher the PF, the more efficient the circuit is because more power can be used,
and vice versa. Factors that can cause PF to be less than one is non-linear load, which are capacitive
load and inductive load.
