Earth is the part of the circuit directly connected to
earth and is at absolute earth or zero potential while
nuetral is part of circuit may not neccasarily be at zero
potential

Answer / alekhya

Earth is nothing but ground,which is a combination of both +ve & -ve paricles(particles may be ions or electrons),whose potential appears to be zero.whereas neutral in the circuit provides a return part,and if there is any problem of high voltages in the circuit the neutral is connected to the ground.

as ac supply is given 2 the transformer why it doesnot depends upon powerfactor????

A powerplant has 8 gensets operating in grid parallel mode. In one genset sometimes there is pf variation and kvar variation. The plant operates in pf mode. When this variation is observed the load is stable, voltage is also stable, freq and genset speed is also stable. How will you check the functioning of pf card. What shall be the ideal output vdc of the pfc, from there it is input to AVR?
