alternating voltage of frequency f are derived and it is shown
that the balance of the bridge is independent of the frequency and
of the presence of higher harmonics. For this the circuit is not
sensitive to ionization phenomena occurring outside of the bridge.
It is also necessary that the investigated object in the left arm
of the bridge and the "standard" in the right arm atust have the
same diclectric properties and electric stresses; they should
therefore be, for example, two identical tratisformcrs, bushings
etc. Now if an ionization phenomenon occurs in a void of the
object or the standard, there is a rapid decrease of voltage on
its terminals. Discharges in the object and the standard
therefore appear on the oscillograph as a set of voltage pulses on
both 6idee of the zero line in each ha.-If period of' the riot voltage.

due to external discharges is negligible. Measurements were also
carried out on a generator coil at 6.3 k%' with shellac insulation.
The experipacntal results sho-w that this bridge is suitable for the
quantitative evaluation of individual discharges in high voltage
objects. There are 13 figuree.

TITLE: Ionization between winding elements of high-voltage
and very-high-voltage transformers
PERIODICAL: Elektrotechnicky" obzor, v. 51, no. 6, 1962, 281-285
'M-Xj~: I ionization in transformer-N-rinding cavities can be
caused by electrical stress not only between primary and secondary
windirtgrs and the core respectively, but also between the elements
of the same winding, i.e. ttrns, coils, or layers. This article
uses a c6pacitarice C2 equivalent circuit to study the ionization pro-.
cess occurring in coils and layers of induct-ion coupled windings
during discharges in the insulation cavity as a result of electrical
stress between individual turns or layers. It was found that the
voltage measured on a capacitor, wired between the insulated core
and the ground terminal of the equivalent circuit, can be used to

distinguish,if a discharge is caused by electrical stress between
Cs;
windiza- elements or between the primary and the secondary winding
and the core respectively. In the first cas *e, the a-c measured on
the capacitor is superposed by a loss which recovers after the dis-
charge, in the second base, the a-c measured on the capacitor is
superposed by a leap which remains until the next diicharge. These
theoretical results were confirmed by practical tests performed on
dry-type coil- azid. layer-wound transformers. There are 14 figures.
