TITLE: Multi-Winding Transformers with Auto-Traniformer
Interconnections (Mnogoobinotochnyyetransformatory s
avtotransformatornymi svyazyami)
PERIOD1,;A-L: Vestnik Elektropromyshlennosti,1959,Nr 2,PP 43-50 (USSR)
ABSTRACT: It is most. economic to use auto-transformers for inter-
connection between high voltage transmission systems. A
high voltage auto-transformer usually has two main
windings connected in series per phase, the phases being
connected in star with earthed neutral. A third winding
connected in delta is then required to improve the
conditions of magnetisation of the core and to compen3ate
the zero phase sequence currents. Since large taree-
phase auto-transformers are made either as a group of
three single phase units or of the shell-type
construction, if there is no winding connected in delta
appreciable harmonics appear in the phase e.m.f.'s- 'The
delta connected winding, which is in any case requ4 -red,
is usually used as a further source cf voltage and
auto-transformer3 used to interconnect electrical 3ySteMS
Card 1/5 usually have three windings and sometimes four or even
five. It is of considerable practical interest to

establish the relationships between the load currents Ir,
the individual windings and the voltages on their termInals
in this case. The problem is considered in this article
for both symmetrical and unsymmetrical loading conditions.
In order to establish relationships between the voltages
and current3 in the windings of multi-winding transfor-
mers it is necessary to be given either the currents or
the impedances of the load and then to find the 'voltages
on the terminals of the windings. In the investigation
of loading conditions it is more convenient to be given
the load currents and in calculations on short circuits tG
assume that the short circuit load Impedance Is zero. In
the case of multi-winding transformers additional
difficulties arise in the calculations because of the need
to determine phase-d13placement between the load 7urrents
in the different windings. A vector diagram of currents
and voltages in one phase of a four winding transformeT J's
given in Fig 1; it is assumed that the magnetising current
is zero and that the currents and voltages in al! windings
Card 2/5 are referred to a single number of turns. Because of the
number of different voltage drops in the wIndIng5 tne

SUV1110-5~-2-11121
Multi-Winding Tran_:f1'.r!f,er.: with Auto-Transformer Interconnecti3ns
voltage vectors are not all of the same phase, but to a
first approximation in calculating the current phajes
this difference between the voltage phases may be
neglected. A complex plane current vector diagram is t2er
constructed in Fig 2 in which the voltage vectors are
constructed along the real axis. A system of equations
Is then written relating tho currents and voltages in a
multi-winding auto-transformer. The formulae can be used
to determine the voltage on the secondary winding of a
multi-winding transformer given the primary voltage and
the load currents in all the secondary windings.
Examples of the U30 of the equations are then given. Tne
first case 1.9 that of a Ste down auto- transf orme r with
four windings on each leg, f-see Fig 3). Equations (9)
and (13) are derived and are then used to construct a
simple equivalent circuit for the four winding transformer
which Is given In Fig 4. It Is then quite a simple
matter to determine the necessary currents and voltages.
The second example considered is a step-up auto-trans-
Card 3/5 former with four windings, see Fig 5. As before. a
simple equivalent circuit Is derived and Is given in

SOV /_' 59-_-~- 11121
1-1ulti-Winding Transfcrmers with Autc-Transfcrmer !n-,er2,.n,-e_--._-n_~
Fig 6. The third example is a step-up four winding
transformer, in which two of the secondary windings are
of the auto-transformer type, see Fig 7. Again, an
equivalent circuit is derived and is given in Fi,- c~
Finally, the transformer connected as shown in Fig 9 is
considered and the equivalent circuit of Fig 10 ~s
derived. The example3 considered cover the main cajes o'
application of a four winding transformer incorporating
auto-transformer connection of two windings with
symmetrical loading. In calculating the externall
characteristics of individual windings it is always
possible to use quite simple complex equations or
equivalent circuits derived from them. The InvestigatJrn
of asymmetrical conditions on a three-phase multi-winding
transformer with auto-transformer connections 13 be3t
done by the method of symmetrical components. The
positive and negative phase sequence currents are b(--t.h
transformed in the same way anJ so for each phase their
Card 4/5 sum may be considered simultaneously. If the zero phase
current is zero the calculations are just the same as

SOV/110-59-2-11/21
Multi-Winding Trar.3f,.rmers with Auto-Transformer Interconnections
under symmetrical conditions. The changes that must be
made when the zero phase sequence current is not zero
are quite simple and are briefly described. A numerical
example is worked out in an appendix.
Card 5/5 There are 12 figures and 2 Soviet references.

Aero of Socialist Labor, laureate of the Statq Prize, As G.
N\~oslf'yan. His scientific oontributions are numerous. During
1931-1934 he developed the theory of the combined synchronous con-
trol circuit with AC commutator generator. Subsequently, he In-
vented the oontaotless selsyn. He was the first Soviet scientist
to publish studies of thYratron-based servosysteme for the con-
trol of elootrioal maohinery. During 1940-1945 he made a major
contribution to the theory of electrical machinery and automatic
control by publishing studies on-the general theory of the also- 12

ABSTRACTs The methodology of synthesis of vibrating systems for balancing equipment is
theoretically investigated. Since the problems of proper instrumentation and isolation
of the balancing equipment from foundation disturbances are discussed elsewhere in this
collection of papers by T. P. Kozlyaninov and V, A. ~Metina respectively, this paper
is concerned prizarily with a synthesis of the mechanical vibrating systems of
balancing machinery and their effective use. In general# the unbalance of & rotor

Purpose of tte current article is to show the insuf-
ficiency of statistical methods for hydrological
C&lcns, by using examples of rivers in Tatar SSR.
Gives a graph shoving the var iat ions 14 flow of a
dMen rivers over the period 1933-1949. Concludes
that it is impossible to det the av discharge for
CZgineering purposes by using entirc series of

Observations without clarifying their character for
