A two phase motor is a motor with the the starting winding and the running winding have a phase split. e.g;ac servo motor.where the auxiliary winding and the control winding have a phase split of 90 degree.

The function of commutator is to facilitate the collection of current from armature conductors. It converts the alternating current induce in the armature conductors into unidirectional current in the external load circuit.

ACSR means Aluminium conductor steel reinforced, this conductor is used in transmission & distribution.

Safety comes first to me. If a safe environment is ensure inside the factory area, productivity will definitely increase proportionately as workers will get a comfortable place to work in.

Whenever an engine is at or below idle with the fuel control switch in RUN. FCOM 1 70.20.8

Say them about your skills and the experience you have in this field. Say them that your resourceful knowledge can prove as an asset for the company.

They measure pressure through temperature, volume of water and steam and amount of energy used by water during vaporization and vice versa.

Dual ignitors are always used for in flight starts. FCOM 1 70.20.8

Beeing an Engineer, I have to serve my nation with my engineering skills, with out the power nothing we achieved so I choosed this as my career.

The currents in the coils connected to a brush are either all towards the brush (positive brush) or all directed away from the brush (negative brush). Therefore, current in a coil will reverse as the coil passes a brush. The reversal of current in a coil as the coil passes the brush axis is called commutation.

It is a procedure that is used for the protection of the workers and the equipments during the maintenance or repair of the power plant.

The purpose of brushes is simply to lead current from the rotating loop or winding to the external stationary load.

When scr is conducting current in forward conduction state, scr will return to forward blocking state when the anode current or forward current falls below a low level called Holding current
Note: Latching current and Holding current are not same. Latching current is associated with the turn on process of the scr whereas holding current is associated with the turn off process. In general holding current will be slightly lesser than the latching current.

I saw myself in many era at last ten years, during at successful project work and troubleshooting of VFD machine.

The Feedback in Control System in one in which the output is sampled and proportional signal is fed back to the input for automatic correction of the error ( any change in desired output) for futher processing to get back the desired output.

Compensation windings are used to neutralize the cross magnetizing effect of armature reaction.

The autostart will make continuous start attemps until the engine either starts or the pilot aborts the start attempt. FCOM 1 70.20.7

I have done very little but what I have experienced is something that brings me fullfillme.

Gate signal is to be applied to the thyristor to trigger the thyristor ON in safe mode. When the thyristor starts conducting the forward current above the minimum value, called Latching current, the gate signal which is applied to trigger the device in no longer require to keep the scr in ON position.

Yes, but with in my knowledge I have enjoy it. But I wants to assist someone means surely I will call them. Because team work makes the difficult things to easier.

Say yes only if you are confident enough with them, they will surely ask you some cross questions on this topic.

Tell that you have proper knowledge about using the power plant and you can also fix almost majority of the technical issues related to it which helps you work independently inside the power plant.

The scientific principles behind the generation of electricity captivated my interest since childhood.

When breaker is close at one time by close push button,the anti pumping contactor prevent re close the breaker by close push button after if it already close.

On time always. Absent only when illness wont permit working.
