The energy generated M sg0o volts.
% cycles, threc-phase, viii be carried
along the east wing of Gstun dam
by heavy cables IN duplicate under
ground lines, and hrough tunnels
under locks, into a Transformer sub
station, situated ON the east side OF
the locks At the Gatun substation,
which is TO be situated az the north
end OF the htll upon which the pres
vnt Atlantic division office building
stands, the electric energy VIII be
transformed from 1900 volts 10 $4,000
volts by means OF stcp-up trans
formers.
The Transmission line viii run from
Cristohal To Balboa, completely across
the lsthmus, permitting distribution
of energy both ways from Gatun. The
line is TO parallel the right of way Of
IA Panama railroad for lis entire
length. Al Cristobai and Balboa viii
be terminal su%bstati0ns similar 20 the
Gatun substation. The terminal sub
stations will receive the energy nj g.
600 volts, less the voltage drop In the
line. ana s~tep-doWn transformers viii
conyert the pressure To 22O0 volts,
which viii be tho distributing voltage
for an circuits. At Miraflores a sub
station will Doe installed for supplying
energy Tor the motors and lamps of
Pedro Miguel and MiraflOres locks.
If electricity is required along the
line the transmission lines will be
tapped by outdoor type o. transform
er substation equipment. This Will
probably bee don az Caimito, TO sup
ply electricity 10 the high power wire
leas station; at Monte LiriO. 10 supply
power 10 the lift bridge. and al ans
permanent town or military reserya-
ron which demands electric lights
and power.
Al Mirafiores the present steam
turho-generators viii be tied into the
permanent electrical system through
2200 volt tie lines extending TO the
Miraflores %suhstation. This steam
station Will scrIe aH "a reserve la the
event the hydro-electrlc station at
Gatun should Dee shut down. In emer-
gcncy. energy from Miraflorcs will
be transmitted back 10 Gatun and to
the terminal -substations at Cristobal
and Balboa, insuring "a continuity Of
services ON the system at all times.
Marvellous Control BOartls.
The centralized control system for
the Panama locks marks "a wonderful
advance in electrical engineering
The locks are operated by electricity
and the controlling switchboards re-
produce la miniature on the board,
by synchronous indicators, every de-
tail of operation. 80 the man Ia charge
sees the complete movement OF an

produced before his eyes. eliminating
any errors which might otherwise
occur.
