Inputs

Standard inputs

  1. Type of short circuit
    The type of short circuit can be chosen among a list of choice:
    • Three phase: the three phases of the stator windings are short circuited.
    • Two phase: the first phase and second phase of the stator windings are short circuited.
    • Single phase: the first phase of the stator windings is short circuited.
  2. Field voltage

    The voltage supplied to the field winding of the machine: “Field voltage” must be provided.

  3. Speed

    The operated speed of the machine to be used in the short circuit test.

  4. Short circuit instant
    The short circuit instant can cause different behavior of the short circuit transient curve. It can be chosen among a list of choice:
    • Instant 0: the linkage flux of the first phase winding is supposed to be maximum
    • Instant 1/4: the linkage flux of the first phase winding is supposed to be zero
    • Instant 1/2: the linkage flux of the first phase winding is supposed to be minus maximum
    • Instant 3/4: the linkage flux of the first phase winding is supposed to be zero
