3. Operands#

The data processed can be divided into two groups:

those concerning a**sing**secondary driver, most often in a**any**position in relation to the main driver but with**several* time intervals. These time intervals can be continuous between them (case of the same current with characteristics different from one interval to another) or discontinuous (case of one or more reclosing at different levels of intensity (keyword factor COUR),

those concerning one or**many**secondary conductors possibly parallel and/or infinite with**a**time interval corresponding to the short circuit and**optional* a second time interval corresponding to a reclosing (keywords factors COUR_PRIN and COUR_SECO).

It can be noted that:

  • in the second group of data, the characteristics of the currents crossing the secondary conductors are treated separately from those of the currents flowing through the main conductor (with the keyword COUR_SECO which can be repeated several times),

  • all cases handled by the second data group can be handled by the first group. However, in the case of currents crossing several secondary conductors, it is then necessary to repeat the operator DEFI_FONC_ELEC with the keyword COUR as many times as there are secondary conductors (and the same for AFFE_CHAR_MECA and CALC_VECT_ELEM).
