Voltage dip transients and auxiliary equipment in nuclear power stations
Voltage-dip transients, oscillations at the beginning and ending of voltage dips, occur due to faults in the transmission system. They propagate to the terminals of auxiliary equipment and may have a negative impact on the performance of that equipment.
Today, there is limited knowledge on origin, propagation, and impact of voltage-dip transients.
The results in this report highlight the significant impact of voltage dip transients on equipment performance. The study concludes with recommendations for further research and measures to enhance equipment immunity.
