Explanation

The pressure in the working fluid cycle of  a thermal power plant is developed by Feedwater pump 

Explanation

A turbine with rated speed of 250 rmp, connected to a synchronous generator, must produce power at 50 Hz .The generator must have 4 poles

Answer D 24 poles Ns=120f/p P= 120f/Ns P= 120*50/250 P= 24

Explanation

The rated voltage of a 3-phase power system is reported as RMS line to line voltage 

Explanation

The insulation strength of a high voltage transmission line is determined by Switching over voltage

Explanation

The precision of an instrument is determined by the closeness of measurement with the true value 

Explanation

The power factor is said to be leading when the current leads the voltage 

Explanation

Power factor correction is the method of connecting a capacitor in parallel with an inductive load 

Explanation

The efficiency of a thermal power plant improves with Use of high steam pressure 

Explanation

A condenser in a thermal power plant condenses steams coming out of  Turbine 

Explanation

 Lignite verity of coal has a lowest calorific value
