Explanation:
Armature winding in a generator is the winding in which voltage is generated. The tappings on the armature winding at intervals of 120 degrees from the side of the commutator indicate that the winding is delta connected. Let's discuss what delta connection is and why it is used for generators.
Delta Connection:
In delta connection, the three terminals of the winding are connected in a triangular shape, where one winding is connected to the next winding such that the start of the first winding is connected to the end of the second winding, the start of the second winding is connected to the end of the third winding, and the start of the third winding is connected to the end of the first winding. The three-phase voltage is applied across the three terminals of the delta connection.
Advantages of Delta Connection:
1. Delta connection allows for higher voltage output from the generator.
2. In delta connection, the voltage across each winding is the line voltage, which is higher than the voltage across each winding in a star connection.
3. Delta connection provides good starting torque and is suitable for generators.
Therefore, the d.c. generator with tappings on the armature winding at intervals of 120 degrees from the side of the commutator is delta connected.
