TO USE MORE NIAGARA POWER.
DYNAMos ORDERED FOR A PLANT ON THE
CANADIAN SIDE.

Another great step in the utilization Of Niagara
power is announced by THE Electrical World and
Engineer" On the American side of the falls the
Niagara Falls Power Company has long had In
operation eleven dynamos. each driven by its own
turbine. and developing 5000 horsepower. A wheel
put parallel with the first one was recently com
pleted, and within the last year orders were given
for eleven water wheels and generators
When these installed the company will be able
to supply 10000 horsepower in the form of cleo
tricty
Operations are TO be undertaken the
Canadian side. THE Electrical World and En-
gineer" says that contracts have just been placed
with the General Electric Company for the con-
OF three 10000 horsepower generators for
the new plant. whose ultimate capacity. it is
estimated will probably reach 10000 horsepower
The negotia tons have been conducted through the
Canadian Niagara Power Company, which had the
original charter for the enterprise, but whose rights
have been acquired by the American company.
These dynamos will be situated. like those OF the
Niagara Falls Power Company. at the level of the
surface the earth while the turbines will be In
wheepit directly underneath Vertical shafts over
one hundred feet long will the wheels
with the generators.
1t is asserted that these dynamos will be the
largest built The closest approach to them is
made by those being installed In the power house
of the Manhattan Elevated Railway Company, of
this city. The latter have a nominal capacity of
5000 horsepower, but designed TO develop 25 or
90 per more in emergency.
THE Electrical World and Engineer supplies the
following additional details:
They are also remarkable on account OF the high
speed at which they will operate. go revolutions

that the machines will have internal revolving
"felds,' while the Older smaller machines have eX-
ternal Fields" and that they will not depend on
transformers for raising the OF the current
from 900 TO about five times that figure for the
line, but will generate themselves current at the
tremendous potential OF 1900 volts. thus dispensing
entirely with expensive transforming apparatus.
The adoption of these enormous units in place OF
the large 5000 horsepower generators previously the
standard Niagara Falls is the result of recon-
mendations made by the General Electric Com
panys engineers, and effects immense saving in
the cost OF this power development. 1t reduces the
wheel pit excavation and the size Of the power
house to about one-half. causes a large reduction
in the of electrical apparatus per horsepower.
and sacrifices absolutely nothing In reliability or
efficiency.
