in the factory or on-site. For the latter tests, the SGVA system
can be mounted in modules on a trailer or installed in an airconditioned weather-resistant tower for permanent outdoor
operation.
Our generator withstands earthquakes and strong winds due
to its extreme engineering design and are also protected
against fire & lightning.
Impulse test system with 4000 kV impulse generator
& divider and 3600 kV multiple chopping gap

APPLICATIONS
Series impulse generators are designed to address all the
rigorous requirements of industry and research. The field of
applications extends form the industrial test facility to
university laboratories and to large-scale research centres for
ultra high voltages.
SGVA impulse test systems can be used to generate impulse
voltages simulating lightning strokes and switching surges.
The total charging voltage ranges from 200 kV to 10’000 kV
with a per stage energy of 10 to 30 kJ. This wide range
permits optimum capacity selection for any test assignment.
The system is built on all our experience acquired in Impulse
Generators since 1932.
Applications covered include testing to IEC, ANSI/IEEE as well
as other national standards.
The basic system can be upgraded in various ways for special
tests or greater ease of operation. A number of optional
additional circuits and components can be included to
optimise the impulse test system for tests on:
