Is there a standard or typical formula to use to calculate forces on switchgear bus based on available fault current.

Can the BIL of individual capacitors be added together in a series group to give a larger overall BIL rating for the entire group to enable lower voltage capacitors to be used?

I cannot find any reference in the NEC that excludes the connection between a close coupled disconnect switch and a transfomer with primary voltage larger than 2000V. I cannot recall seeing any field installations that have shielded cable connections between the disconnect and the transformer...

Does anyone know if there are any courses available for the SKM transient stability module? If not could anyone sugggest some other courses that could assist with theory of transient stability analysis and computer modeling?

When doing an AC short circuit study, do DC motors contribute to fault currents and therefore need to be included when building a system?

I am doing a motor starting study and with Full Voltage start I am getting around a 12% drop at the bus. I want to do a reduced voltage start with series reactance, could someone give me some assistance on how to go about sizing the reactor to reduce the voltage drop. Thanks
