Answer Posted / nikhil
AVR is automatic voltage regulator.as the name shows it
regulate the output voltage of regulator. in fact it is a
card that sense the output voltage of a generator and a
signal is giving to an exciter (an exciter is an dc or ac
generator)and thus the excitation is giving to the rotor of
generator.hence it maintains the output voltage of generator
thereby it prevents the overload.

Hi Suppose we have a wye/wye transformer which is grounded at both sides,in this situation, do we have ay ground transformer? in other words, ground transformer can do any thing more (while we have nuetral wire in both sides)? As the last question, what about 3rd harmonic? we have two choices: first using wye/delta transformer + ground transformer and second using wye/wye earthed connection.in the former choice, we dont have 3rd harmoonic at the secondary side but what about Yn/yn conection? do we suffer from 3rd harmonic in the Yn/yn connection?

what do you mean by every IC 74 first digit.why are you using this no.why not using another no.
1. The DC generaror,s induced output emf is connected with a DC motor(as load). when increasing the load of the motor by using brake drum or any way. what are the parameters will changes in both motor and generator(voltage, current, resistance, frequency, speed, torque, power, flux etc...) 2. Similarly for AC generator and AC motor 3. similarly if using DC batteries instead of DC generator, What happens?
can we use engine degreaser for electrical motors?
