This condition was eliminated by use of thermoset windings. But the problem has recurred on post-1970 small (less than 20 MW) coil-wound generators that were made with an inappropriate asphalt material (Fig 18).

Webb26 apr. 2024 · A generator alternator contains an assembly of both moving and stationary components encased in a protective housing. The stationary part of the alternator, also known as ‘stator’ is a set of wires, or electrical conductors wound in coils over an iron core. The rotor also known as the armature is the movable part of the alternator that ... WebbIn a shunt-wound generator, the field winding is connected across the armature winding forming a parallel or shunt circuit. Therefore, the full terminal voltage is applied across it. A very small field current I sh , flows through it because this winding has many turns of fine wire having very high resistance R sh of the order of 100 ohms.
