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.

  1. 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.
  2. How to trace to identify the low insulation?
    To trace the low insulation by switch of one by one switch breaker when the low insulation there the indicator will back
    to normal. Then we need to check the breaker which low insulation by merger test the equipment though that
    breaker

    ● Turn the helm wheel to control the steering follow the bridge order
  3. What is the used of expansion tank?
    Expansion tank used for engine cooling water, the tank is collected fresh water from engine cooling system, so the
    cooling water can keep required temperature also we can check the salinity of the water if there is high
    salinity we can put the chemical treatment for the system.
  4. What is benefit of ECM/ engine control module?
    ECM is a type of electronic that control a series of actuator on an internal combustion engine to ensure optimal engine
    performance. And inside the ECM there is sensor which can read the engine parameter.
    So the benefit of ECM is make the engine have optimal performance and make the engineer or operator easy to read
    the parameter of engine while running.
  5. 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.
  6. 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.
  7. 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.
