modelForcedCommSwitch

Forced commuting switch, 1-phase

Extends from Base.Units.NominalVI (Nominal values).

Information

Allows switching of single conductor (of totally one or two).
Switching by forced change of current-voltage ratio.

'closed' and 'open' determine the mechanical switch-position.
Electrically the switch is 'on' if it is 'closed', whereas the currents start decreasing exponentially, when it is opened.

The transition between the 'off' conductivity (epsG) and the 'on' resistivity (epsR) is continuous with an exponential relaxation function

  f = (exp(-dt^p/2) - exp(-1/2))/(1 - exp(-1/2))

with

  dt          relative time measured from switching instant
  t_relax     relaxation time
  p           power of exponent
