The
company’s
Hybrid
HVDC
breaker
–
which
marries
ultrafast
mechanical
actuators
with
semiconductor
IGBT
valve
technology
–
can
interrupt
power
flows
equal
to
the
output
of
a
nuclear
power
station
within
five
milliseconds,
says
the
Swiss-based
group.
The
technology
will
allow
variable
sources
of
electricity
to
be
better
integrated
into
operating
grids,
as
well
as
boosting
an
HVDC
transmission
network’s
reliability
by
protecting
it
from
power
outages,
ABB
adds.
The
engineering
group
claims
grids
built
with
the
new
breakers
would
be
able
to
interconnect
and
load-balance
between
HVDC
“superhighways”,
integrating
renewables
