Answer / shahbaz shaikh

as the load increases means motor draw more current from supply to satisfy the load torque up to the saturation region speed is inversely proportional to the load current hence as load current increases speed is decreases
in case of synchronous motor as load increases there is no effect on the speed but there is change on the operating power factor of load and load angle is change with load but speed remains constant

I have a current transformer with 1 main reading meter with transformer outside the building and a control panel having 5 CT reading meters with black round coils inside the building. I want to know, A) when current pass through the Transformers, will the current be reduced or be the same and after that B) when current pass through the CT meters with black round coils, will the current be reduced or be the same. C) in the above process will the reading of the main meter be same or different, from the total reading of all the 5 CT meters.
