motor start calculations

100 % definition of motor start effects on system known already in the design phase, avoiding surprises after startup. With this knowledge ostly refurbishments are prevented.

An additional benefit is knowing the effects on other equipment in advance.


  • calculation of voltage dips at the supply point and in the distribution system

  • reactive power drawn from the supply grid

  • calculations with actual motor loads

  • verification of torque available during motor start
