helo people,

i am observing Behaviour of the current on a symmetric tree phase system. the max current at the load ist 1A and i dont understand why the red current ist -1.22 AT THE SIMULATIONSBEGINN. it seems like a current mismatch at the beginn. how i can solve that?i calculate the initial current from inductance within the phase

thank in advance

You are calculating the initial current flow incorrectly. Currently, your simulation assumes the current is in phase with the voltage. However, there is a phase shift due to the RL load. Please look at the Simulation + Simulation Parameters + Initialization tab for an example of how to calculate the initial three-phase RMS current, and then the instantaneous current for each phase.
