Experiment- 1

OBJECTIVE

To study the Synchronization of the alternator with infinite bus bar.

EQUIPMENTS REQUIRED


  1. DC Motor - Alternator Set
  2. Voltmeter-1
  3. Rheostats-2
  4. Tachometer- 1

CONNECTION DIAGRAM

Fig 1.1:Connection diagram for synchronizing the alternator with 3-lamp method

PROCEDURAL STEPS
  1. Make the connection diagram as shown in figure 1.1
  2. Run one of the alternators and adjust its voltage at rated value and close switch  to bus bar.
  3. Start the second set (alternator 2), bring it upto proper speed equal to that of the running alternator (or bus bar voltage).
  4.  Synchronize the incoming alternator by any one method described in theory.
