All the power source it may be transformer or Alternator
(DG-DC power generator).
For parellel operation synchronisation is important. I.E
Voltage level, frequency, phase angle should be equal for
the both sources.
For checking the synchronisation previously DARK LAMP
METHOD was used. Now a days special relays used for this
purpose. Relays MES 120(Schneider), 7UT relays in Siemens.

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.
