The eleven thousand horsepower 3800 volt three phase motor at the refinery was a real trip when starting...
General notification went out hours in advance to all refinery process units to minimize usage. PG&E Pacific Gas and Electric boosted nominal distribution voltages to achieve 260 volts phase to phase, a few minutes before startup.
Then right out of a movie scene in a prison when "The Chair" dimmed the lights in prisoner cells, voltage slumped by 10-15 volts phase to phase.
I forgot the motor-start time limit. It was something like 15 seconds. The stator resonance shook a three foot thick unit concrete pad. About a third of the time the isobutane compressor failed to cycle. The motor was shut down and had to cool for seven hours before a re-start was attempted.
The start switch used a pump. A U-Handle with a foot long grip prong. About a dozen pumps in all. The contact lever had to be pushed up and with a BANG the contactor closed. The smell of ozone permeated the air.
Shell ended up purchasing the PG&E brick generating plant located on Shell Avenue. 28 Megawatts.
After seeing this, regular motor starting shrank in perspective :)
Wow, that must have been a scary thing to be around when trying to crank it up.
