I can imagine what it feels like standing near them as the cement floor literally shakes you up to your eyeballs. We had lightning issues being at the top of a mountain so we had huge isolation capacitors. It phased the circuits by discharging the capacitors in sequence.

ok, to anyone who’s … ok, to anyone who’s heard the 64foot stops recently, what it’s like? i’ve never heard a 64er myself, does it shake thee entire hall? and it’s a big hall too? i’ve heard it makes people feel nausus? do the seats shake?

Startup of the three blowers in the main blower room. 100 inch compressor, low pressure and high pressure.

Wow how many RPM and what torque? Do they start on one voltage but run on another?

What voltage(s) do the motors run at? 416, 480, 4160? or something else?
