I have earlier posted about the failure of capacitors in a pumping installation vide thread Link. Recently we have a observed a pattern of loosening of bolts/nuts in several starter panels where the capacitors are mounted. Under these structures discharge lines passes through for a short line before draining the water into canal. We feel that loosening of bolts/nuts is due to the vibration of building/structures due to pumping. Does this mechanical vibration (building/structures) have any relation to the capacitor failures?
