Product Description

The operation of connecting an alternator in parallel with another alternator or with common Bus-Bars is known as synchronizing. Generally, in power transmission & distribution many alternators operate parallel in synchronization with the bus bars. Thus, the alternators remain connected to a live system of constant voltage & frequency. It is never advisable to connect a stationary alternator to live bus-bars, because stator induced e.m.f being zero, a short circuit will result. For proper synchronizing of alternators, the following three conditions must be satisfied

  • The terminal voltage of the incoming alternator must be the same as bus-bar voltage.
  • This can be indicated by a volt meter (V).
  • The speed of the incoming machine must be such that its frequency (PN/120) equals bus-bar frequency.
  • This can be measured by a frequency meter (Hz).
  • The phase of the alternator voltage must be identical with the phase of bus-bar voltage. It means that the switch must be closed at (or very near) the instant the two voltages have correct phase sequence.
  • This can be measured by synchronizing lamps or Synchronoscope.
