OVERVIEW
ASD developed a high
current impulse
generator which was
implemented in an
automated arrestor
test system, at Raycap,
SA in 2006; a
manufacture of surge
arrestors and
others, in
Drama, Greece. The
generated impulse
could reach 200KA.
One of the functions
that the arrestor
test system
achieves, is an Impulse test on MOV at production
line level and at
research level,
including
synchronization and high current testing.
The required high
current impulse is
generated through a
set of parallel
capacitors charged
by a high voltage,
low direct current
source and
discharged through
resistances,
inductances, unit
under test by a
spark gap. A well
designed switching
circuit allows the
open & close of
appropriate switches
so that capacitor
banks can be charged
and discharged at
right time. The
system is
accompanied with a
reliable software
that communicates
with PLC and
controller to
control the hardware
functions. Check
Automated Arrester
Test System
for further details.
The impulse
generator utilizes
three capacitor bank
levels: 8/20µs, 2ms
and 10/350µs due to
the application
requirements. This
product can be
customized and
redesigned due to
other client's
applications
requirements.
