The necessary condition for parallel operation of two alternators is Correct Answer All of these

Necessary condition for parallel operation of two alternators:

  • The phase sequence of the busbar voltages and the incoming machine voltage must be same
  • The busbar voltages and the incoming machine terminal voltage must be in phase
  • The terminal voltage of the incoming machine and the alternator which is to be connected in parallel or with the Busbar voltage should be equal
  • The frequency of the generated voltage of the incoming machine and the frequency of the voltage of the busbar should be equal
