The inertia of these spindles is SO
great. and the friction so trivial, that
It requires 26 minutes for them to
come to a full stop with the load on,
after the steam has been shut COM
p1etely on. With the load removed
they would revolve an hour and one
half with the steam. The turbines
utilize about ITO pounds OF the boiler
pressure, to which is added vacuum
pressure of about % inches. the
water is used over and over again
through the condensing system as
West Fork water is miserablE impure.
The two larger generators develop
900 amperes, $500 volts, three phase
alternating current; the smaller ones
go amperes, three phase with same
voltage. with guaranteed overload
ing capacity of 100 per cent. The cur

requirements.
In the Jayenn plant a part OF 1t Is
transformed to $4,000 volts and sent
