Transformer: answer key, IEC style, sheet 2 of 2

  1. Fig. 1

    P1P2S1S2

    Name Transformer

    The separate-winding transformer shown here transfers energy magnetically between windings without an internal conducting connection between them. This description excludes an autotransformer, whose windings share a conducting connection.

  2. Fig. 2

    P1P2S1S2CT

    Name Centre-tapped transformer

    A centre tap is an electrical connection at the midpoint of a winding, shown as an extra lead from that winding.

  3. Fig. 3

    P1P2S1S2

    Name Air-core transformer

    In the transformer drawings here, parallel lines between windings indicate a magnetic core, drawn as iron-core examples. The air-core example omits these lines; another drawing's legend may use a plain coil more generally.

  4. Fig. 4

    P1P2S1S2

    Name Transformer

    The separate-winding transformer shown here transfers energy magnetically between windings without an internal conducting connection between them. This description excludes an autotransformer, whose windings share a conducting connection.

  5. Fig. 5

    P1P2S1S2CT

    Name Centre-tapped transformer

    A centre tap is an electrical connection at the midpoint of a winding, shown as an extra lead from that winding.

  6. Fig. 6

    P1P2S1S2

    Name Air-core transformer

    In the transformer drawings here, parallel lines between windings indicate a magnetic core, drawn as iron-core examples. The air-core example omits these lines; another drawing's legend may use a plain coil more generally.

Notes

  1. Answer key for sheet 1. The Fig. numbers match the exercise.
  2. Rotating or mirroring a whole symbol, with its terminal identities and connections preserved, does not change the component. The terminal labels move with the drawing.
