TITLE:- Determining the Maximum No-Load Current of Transformers and the
Charging Current of 110- and 35-kv Lines Cut by Type RLN Disconnects
PERIODICAL: Naladochnyye i eksperim. raboty ORGRES, Nr 15, 1958, pp 156-163
ABSTRACT: To determine the possibility of adopting the substation schemes without
circuit -breakers on the high-voltage side, ORGRES jointly with large power
systems (Lenenergo. Mosenergo, and others) staged tests intended to determine
mazdrxxuzn currents and thereby rna--dmurn power of transformers and also
ma:;dmum length of a transmission line that could be reliably cut off at no-load
by a type RLN disconnecting switch. In addition to visual observations, a
cinema. filming was made which permitted determining the duration of arcing;
to determine accurately the moment of arc extinction in relation to the angle of
the disconnecting blades, both the current being interrupted and the blade

SOV/112-59-5-8849
Determining the Maximum No-Load Current of Transformers and the Charging
movement were recorded by an oscillograph. Overvoltages set up by cutting off
no-load lines were not measured. The tests enable one to draw the following
conclusions: The voltage, maximum transformer capacity, and transmission-
line length which could be cut off at no-load can be considerably increased over
those apeci$ied by the PTE M.ES standards. No-load currents as high as 7,amp
for 20-Mva, 38-kv transformers and 10 arnp for 31.5-Mva, 110-kv
transformers can be cut off by a RLN disconnect. It is recommended that the
disconnects be operated on or off quickly. Pole separation of the disconnect
should not be less. than 2, 500 mm for 110 Jxv and 1, 200 mm for 35 kv. To
determine the maximum no-load length of 35- and 110-ky lines that could be
cut off by the disconnect, overvoltages accompanying the line interruption need
to be studied.

Abstract The effectiveness of an allergy skin reaction as an index of the
immunity produced by a live anti-plagrue vaccine was investigated.
A killed vaccine made from strain Ye V plague bacteria grown in
a -3imple agar culture medium was used as the antigen. Pestinwas
used as the allergen. The results of the experiments are presented

ABSTRACT: Eqjations are analyzed that describe the motions in hydraulic follow-

differential and nondifferential power. cylinders, with flow-through, with two-.
edge, and one-edge slide valves. An approximate method for computing
parameters of such systems is suggested; the method is based on linearized
equations of motion. Influence of the system parameters upon its stability is.
investigated by means of the Vyshnegradskiy diagram for systems of the third

TEXT: In the present article the authors analyze the problem of sta-
bility and of dry friction in the follow 'up systems in these instal-
lations on a fitrictly theoretical basiso For increased accuracy in
determining the behavior of the system In an oscillatory statep the
saturation characteristics of the piping is introducedras condi-
tioned by the finite pump output. In solving the problemp use was
made of the electronic analogue (MN-M). To evaluate the accuracy of
the results obtained the same analoguefv~,was used to obtain the so-
lution of the Vyshnegradekiy problem which was in complete agree-

A.G. Mayer. The present article is reatricted to analyzing the in-
fluence of dry friction and that of sixt-uration resulting from the
finite output of the pump. The linearized equation of the system
