across a series of gulches and ridge:
to the opposite side of the island. Ant
in the setting of the poles the utmost
ingenuity was displayed by the engi
neers. One is amazed to see poles in
positions which are remarkable fol
their apparent inaccessibility. Horses
and mules could net carry them up
Machinery, ropes and pulleys had moth
ing to do with this phase of the under
taking. Strong-limbed japanese per-
formed the feat of conveying these
heavy poles up the ridges. From six
to ten men raised pole to their
shoulders and necks. Digging their
toes into the earth and moving slowly
upward on their hands and knees the
burden-bearers finally took the poles
to the places assigned them. And all
this was done without an accident.
bitches, TUNNELS, GENERATORS
On arrival at the power house Engi-
neer Robertson, in charge of the plant,
requested those who desired to con-
sA""0 oh ~ tHS intake, TO proceed at
once by horseback. A large number in
the party. availed themselves of this
opportunity despite heavy rainfall up
the valley. The commencement of the
bitches and tunnels was found inter
esting: Seven miles from the steamer
landing the series of waterways begin.
At an elevation of 725 feet the water
is led along the bed of the Wainiha
river, heavy stone spillway 100 feet
In length having been constructed in
the stream. just below this is three
foot SYNDICATE and below this are three
headgates, each three feet in width,
having a rise of SO feet.
The ditch proper begins below the
headgates and is graduated down from
nine feet at the bottom, to four feet,
with thirteen feet of width at the top.
The tunnels are 6x6, all having arched
tops. There is a. decline of zen feet to
the mile throughout the length of
bitches and tunnels, giving rapid
flow. Thirty-three tunnels were neces-
sary to convey the water, these having
an aggregate length of 1850 feet. To
this is added the 10000 feet of ditch
way which brings the water to the
forebay at the end of the last tunnel |
at an elevation of 655 feet above the !
powerhouse.
A pipe line runs from the forebay to |
the power-house down the slope of the |
mountain, making line 100 feet in
length. Two pipe lines of decreasing
diameter bring the water to the water I
wheels. Each pipe line supplies one of
the water-wheels, which have direct |
connection with alternating current |
generators of 1900 kilowatt capacity |
each. The wheels are the Pelton type
and the stream of water from the pipe T
comes in contact with concave discs
set in the periphery. The generator is
mounted between two bearings on a
shaft. The nozzles are provided with
controlling needle for hand control.
There are two of the large units of
tion to these there are two seventy
kilowatt, direct current, 125 volt gem
orators connected to Pelton water
wheels, used as exciters to produce
magnetism in the large 1900 kilowatt
generators.
The current is taken from the main
generators to a switchboard and this
switchboard is SO arranged as to con-
troll the flow of current through what
is known as step-up transformers /,
These transformers are six in number,
with one to spare. They receive the
current at 220O volts and step it up to
33 900 volts Ii
The current leaving the transformer t
house passes through high tension con-
troll switches and lightning arresters
and goes into the main line ,
MEN WHO WORKED. I
Mr.. Grant of the Westinghouse Com
pany was in charge of affairs. John s
trician, was in the power-house and
Cassidy, the well-known veteran cleo
mas had much to do with the instaila-
Jon of the electrical work. Mr.. Grant c
has had a wide and varied experience
n the installation OF power plants on t
he mainland.
AIonzo GartIey, manager of the Ha- +
vaiian Electric Company, however, has i
,een the prime organizer of the entire
system His company obtained the v
contract for the whole proposition-one II
which has cost the Kauai Electric t
Company about $500 .oo0-and under his b
Erection the entire work has been car L
led out. The Hawaiian Electric Com s
,any is the agent for the Westing-
louse Electric Company and it's gem n
traitors. and, in fact, the latter COM j
,any's devices have been Installed Il
and everything has worked
IS smoothly as the most critical judge
ould wish for. Mr.. Gartiey has oeen
in his work to make the
proposition successful, and SUCCEEDED
admirably. :
