Answer Posted / ambat
The transformer winding temperature measurement is a
complicated procedure since we cannnot place any sensor on
the surphase of the winding.So normally a WTI CT is
connected with suitable ratio and the secondary current is
used to heat a resiistance kept inside the thermowell
filled with the same oil.the resistance used for this will
be of the same thermal characteristic of the transformer
winding wire to get the thermal image.Then temperature of
the heated oil is measured by using RTD or any other
temperature measuring device.SO many other elctronic
devises are also now available. but in all devices WTI CT
are essential

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?
