Lavals Ångturbin, manufacturing the well known
steam turbines invented by Dr. Gustaf de Laval.
The same firm also makes turbo-generators and other
electric materials. Another similar firm is Luth &
Roséns Elektriska A. B., founded in the 1880-s and
noted for electrotechnical and electromechanical
productions, among which helicalgeared motors of a
special design are highly appreciated.
Elektromekaniska Industriaktiebolaget in Hälsingborg is third in
order among the manufacturers of heavy machinery.
Among other firms should be mentioned the
Elektriska Aktiebolaget Volta close to Stockholm,
manufacturing heating apparatus, vacuum cleaners, electric
boilers, etc., the Aktiebolaget Elektrav erken,
Stockholm, making similar products and also incandescent
lamps, the Aktiebolaget Skandinaviska
Glödlamp-fabriken in Nyköping, making electric lamps, the
two accumulator factories AckumulatoTfabriksaktie-
bolaget Tudor and Svenska Ackumulator-A. B.
Jungner, representatives for the manufacture of lead and
alcaline accumulators respectively, the latter on the
basis of the inventions of the Swede Jungner.
Although the electrical industry of Sweden is not
regarded as among the largest industries of the
country, it is very important. The aggregate share
capital involved is about 250 mill, kronor. Since the
war, the electrical industry has assumed a more
international character, and this is making further
expansion likely, which will have an important influence
on our trade balance.
ELECTRICITY AND ELECTRICAL DEVELOPMENT
IN GREAT BRITAIN.
By Llewelyn B. Atkinson, Director, Cable Makers’ Association and member of British
National Committee of the International Electrotechnical Commission.
The opportunity provided by the
meetings of the International
Electrotechnical Commission in Stockholm is
a favourable one for the publication
of brief reports from the different
countries, and your invitation to
submit a few words in regard to
electrical development in Great
Britain is welcomed.
When the question of electrical
progress in a country is under
consideration, the fact that Great Britain covers
a relatively small area of land and ha 1
developed other utilities to an
advanced stage at an early date makes it
desirable to issue a caution that conclusions drawn
from comparisons between information presented
from different countries require very careful scrutiny
before they can be taken to represent the true relative
position of development. No attempt, therefore, is
made here to give statistical information as to growth
and progress.
It may perhaps be stated that the most important
step in the development of the use of electricity in
Great Britain during recent years has been in
connection with the organisation for the supply and
distribution of electric energy throughout the country.
Water-power being practically non-existent,
electric supply in the early days developed on the lines
of a small generating plant for every locality, leading
to the use of a number of different distribution
voltages and frequencies. After prolonged enquiry and
investigation, is was decided to standardise the
distribution voltage for this country
at 230/400 volts, three-phase, 50
frequencies, and a change from all
existing voltages and frequencies to
the standard voltage is being made as
rapidly as is economically possible.
This is being encouraged by the fact
that there is now sufficient use of
this voltages in this country to enable
manufacturers to supply lamps,
accessories and apparatus for the
standard voltage at somewhat lower prices
than it can be supplied for the
nonstandard voltages.
Since the year 1926, the
organization of the electric supply industry in Great Britain
has been on a new basis. Under the Electricity
(Supply) Act of 1919, an administrative body termed
the Electricity Commissioners was appointed to
promote, regulate and supervise the supply of electricity,
and was given important statutory powers and duties.
This body was charged with the responsibility of
dividing the country up into electricity districts, and
was given control over the establishment or extension
of generating stations, and main transmission lines,
and the granting of powers to undertakers to provide
a supply of electricity.
In 1926, a further development took place in the
appointment of a Central Electricity Board, which
was given the responsibility of putting into practice
the general schemes indicated by the Electricity
Commissioners. The policy followed has been to
retain the largest and most efficient stations, and
