Complete Specification Left, 28th Aug., 1896-Accepted, 17th Oct., 1898
[Communicated from abroad by Messrs. SIEMENS AND HALSKE, of Berlin, in the
German Empire, Electrical Engineers.]
Improved Means for Compensating Variations of Load at Electrical
Stations.
We, SIEMENS BROTHERS & Co., LIMITED, of 12, Queen Anne's Gate,
Westminster in the County of London, Electrical Engineers, do hereby declare
the nature of this invention to be as follows:-
This invention relates to the method of compensating variations of load at
electrical stations described in the Specification of Patent No. 16028 of 1893.
In working according to the method there described the disadvantage may
happen that the space required for the field magnet winding of the auxiliary
machine is so great that this machine has on this account to be made considerably
larger than is required for the work it has to perform.
The present invention has for its object to obviate this difficulty; it consists in
the employment of a special exciting dynamo for exciting the auxiliary machine
described in the said specification, the field magnet windings of which exciting
machine are connected in the same manner as are those of the auxiliary machine
described in the said specification.
The electromotive force of the auxiliary machine will then also vary as regards
its direction and amount simultaneously with the variations of the intensity of the
current flowing to the distributing network, as in the original arrangement, and it
can be chosen considerably smaller than was possible under the conditions described
in the said prior specification, and in addition, there will be much less expenditure
of energy required for exciting the field magnets during the working.

nature of this invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement:-

The accompanying drawing shews diagrammatically the above described arrange-
ment the several parts being designated by the same letters of reference as the
corresponding parts in the drawing to Specification No. 16028 of 1893, while the
exciting machine provided according to the present invention is marked S.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
:―
In combination with the means for compensating variations of load at electrical
stations, described in the Specification to Patent No. 16028 of 1893, the use of
a special exciting dynamo for exciting the auxiliary machine there described, the
field magnet windings of which exciting dynamo are connected in the same manner
as those of the said auxiliary machine, substantially as described.
