Industrial installations are often highly sensitive to voltage dips. Traditional analysis of voltage dips, defined by reduced voltage over a short duration, usually does not reveal all the details of the impact on connected devices. This study focuses on detailed voltage dip modelling, particularly the transients at beginning and ending of the dip. The propagation and amplification of these transients have been analyzed for four fault types in a transmission system. Results indicate significant transient amplification in the industrial distribution grid, especially during three-phase-to-ground faults when the on-site generator is off. The impact of voltage dip transients was assessed for common industrial devices, induction motor, diode rectifier, and voltage source converter. These findings provide valuable insights into voltage dip transients and their effects on low-voltage devices, supporting the need for further studies into this phenomenon.
