Thank > You Yours could be an interesting structural problem, especially if the capacitors are rated for pulse discharge service. The typical Lorentz force reactions (attractive and repulsive) on pulse-discharge capacitors and their busbars during a discharge could produce sharp impulse loads well in excess of 10 tons. I have witnessed a busbar support failure where three 5/16 GR8 bolts failed in tension. Usually these forces are resolved within the capacitor framework; however if bushings supporting the high-current busbars are mounted directly to the foundation instead of the capacitor frame, significant concentrated stresses could develop where the support bushings meet the foundation. -- -GL www.lod.org
