Volt

Liberia's new electrical system will be compatible with 220 volt European systems.

If the volt, ampere and ohm were taken as the absolute units, the practical units would be the ampere, begohm and begavolt, names just as convenient as ampere, coulomb and farad.

The system voltage is 630 volts d.c. and the supply to the trains is by top-contact third rail with running rail return.

Each turbogenerator consisted of a steam turbine, powered by 900 psi of superheated steam, that was coupled by a set of reduction gears to a General Electric marine alternating-current generator operating at 1,800 rpm. Each generator had a capacity of 2,000 kilowatts of three-phase power at 450 volts and 60 hertz. The main 450-volt switchboard was energized by the two turbogenerators. The emergency switchboard, in the emergency generator room, was fed from the main switchboard through an electrical tie.
