1) bus cuplour is nothing but the elctrical brekar which
couple the two busbar in electrical PCC. because of this
avoide electrical breakedown in continues plant.

Answer / somnath chakraborty

A bus coupler is generally a circuit breaker which helps in connecting one bus to another thereby enabling uninterrupted supply in the event of fault in one bus.Switch over from one bus to another can be done either in auto or manual mode.

Answer / murali

Buscoupler is nothing a but a breaker which is medium of
the two source(two I/c) and it operate while absent of
eightr one i/c for uninterruption supply to Load

If Both I/c ON Buscoupler should OFF,
If any One OFF buscoupler should ON

Answer / charles

The main function of Bus Coupler is to couple the
busbars.It can also works as protective device.

The function of alternator is to generate power.It will
convert the machanical energy to electrical energy.

Types of DG oils are like 15W40,20W40 etc...

Answer / dhruv

bus coup. is used to couple two bus basically it is used to
give a continous power to consumer in case there is fault in
one of the bus

Answer / shy11am

1)The bus coupler is a protection device including of
Circuit breaker and Isolator,it is connected between two
Bus for Load variation purpose,


2)the main funtion of alternator is generate electric power
by converting mechanical energy(Steam).

Answer / ali

Bus cuplour is a device use for coupling two bus bar for the purpose of avoiding the interruption to consumers,since one of them(bus bar)are in abnormal condition.

Answer / shri..

Above answer is right
2) The main function of alternator is generate the electric
power.

3)Engine oil have grades example 20W 40W & its depend upon
the engine manufacturar.

Answer / suresh

Bus coupler is device it is use like a switch without any
interuption power supply
DG oils 20W,40W its 4types

We have a 12MW power plant & we inject 5-6MW power to Orissa GRID. For this we have a 33KV/11KV switch yard having 12.5MVA power transformer. Some times we draw power during emergency. It is observed that during Export or Import for load less than 500Kw the power factor is decreasing to 0.3 . This is happening only during export or import. During island condition TG power factor OK.Our capacitor bank is provided with our Power plant auxilliary load. Please suggest how I can we improve our power factor during low load (GRID).
