Answer Posted / darshan chaudhary
in the transformer there are two winding first is primary
and second is secondory,if third winding is also used in
transformer for specific purpose,that is called tertiary
windingits purpose is that,
(1) it permit third harmonic curret to flow,this reduce
third harmonic voltage
(2)sometimes there is need to interconnected to
three transmission line
(3)for measuring the voltage of HV
testing transformer

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?
