TITLE: Cutting the Loss Angle of Capacitor Paper Used in Power Capacitors
Employed on Long Transmission Lines
PERIODICAL: Tr. Mezhvuzovsk. nauchno-tekhn. konf erentsii po dal'nim.

ABSTRACT: The problem of raising the capacity (power) of a unit capacitor
intended for large reactive-power banks is considered. A formula is derived
that shows the relations between the capacitor temperature rise, its tgS' , and
its rated reactive power; cutting tgE by 2076 permits doubling the capacitor
power. The capacitor tg~ can be slashed (at 50 cps) by cutting down the tgg
of its paper. A short summary is presented of an investigation of the capacitor-
paper tgi~ for organic and inorganic paper compositions; the investigation was
carried out by the Chair of Electrical -Insulation and Cable Engineering, LPI.

TITLEs Foil Condensers (Plenochnyye kondensatory)
PERIODICALt Elektrichestvo, 1957, Nr 9, PP- 75-79 (USSR)
ABSTRACTt A survey is given on the world production and a detailed de-
scription of the state of development of foil condensers in
Europe, USA and Soviet Russia. The United States, where polar
and nonpolar foils are used, are the leading country in this
development. Dielectrics of the second group are polystyrene,
polyethylene, and polytetrafluorethylene which show a smq~Xl lose
angle of (2 to 5)10-4 as well as higher resistance of 10'7 to
10 0 Ohm.cm in comparison with infiltrated paper. Polysterene is
used for condenser building also in Europe however it is not so
heat resistent. Polytetrafluorethylene (Teflon) is much more
expensive, however, as an organic material it shows exceptionally
high working temperatures from 200 to 2500. The advantage of
these polar synthetic foils compared to the nonpolar ones is the
higher dielectricity constant and a higher electric strength. The
following polar foils are used at presents cellulose acetate,
polytrifluorchlorethylene, and polyethyleneterephtalat. On the
basis of the first mentioned,condensers are produced by the

with increase of the latter (Fig 7). This is reflected
in the State Standard, which requires tan 8 of KON-1
paper with usual density to be less than 0,0017, while
for the paper KON-11 with higher density tan b should be
below 0.0020. If the density of capacitor paper is
lowered, then its dielectric losses are decreased but
the process lowers the electric strength of the paper
as well (Ref 7). The latter effect can be avoided by
a suitable pulping process (Ref 8) and lowering of the
amount of conducting particles in the capacitor paper
(Ref 9).

TITLE: Dielectric Losses in Condenser Paper (Dielektricheskiye
poteri v kondensatornoy buma6e)
PERIODICAL: Elektr-ic':Iestvo, '1958, Nr 9, PP 47 - 52 (USSR)
ABSTRACT: In recent years investigations of the dielectric
losses in condenser paper were carried out at,the
Laboratoriya ispytaniya dielektrikov LPI (Laboratory
for T,!stiJ-,,g Dielectrics at the Leningrad Polytechnical
Institute) in collaboration with the scientific research
institutions of paper industry (TslTIIB, UKRITIIB) and
with the Kafedra khimii tsellyulozy Leningradskogo
tekhnoloGicheskogo instituta (Chair of Cellulose Chemistry
at the Leningrad Technological Institute). A special
method of measuring loss angles operating with a simplified
electrode system was developed (Ref 2). Paper samples are
dried in vacuum and thus the development of an ionization
in the paper is eliminated. This method was introduced
Ca-rd 1,13 into the Ukra-L*nskiy nauchno-issledovatellskiy institut bumagi

Dielectric Losses in CondenL3er Paper
(Ukrainian Scientific Research Institute of raper),
being also adopted iuith few alterations by the new GOST,
which aas recently officially authorized. This method
not onl.. D it to establish a preliminany standard
for the tg of condenser Dauer but also to pool information
on t-e functions of the loss angle versus a number of
factors and to show ways and means to improve these
orinci al functions. Sumraary: 1) The loss angle of dried
p
condenser paper is an important criterion of Dauer
quality. 2) A perfection of domestic sulfate cellulose
tending to reduce the pentosaare content does not enhance
une loss-an.-le quality of condenser paper, but, on the
contrary, leads to an increase of the loss angle. 3) Ash
ca.-aposition is oneof the decisive f-:ctors governing the
majnitude of the loss aangle.~; 17donovalent metals, sodium
in particular, exert a distinctive detrimental influence.
