SCT013-000 CT 100A Non-invasive AC Current Sensor
SKU: B140,D07,IMP30,L10,Th15,KRT131+514
SCT-013-000
is
a
Non-Invasive
AC
current
sensor
i.e.
it
is
a
current
transformer
which
can
be
used
to
measure
AC
current
up
to
100
amperes.
Current
transformers
(CTs)
are
sensors
that
are
used
for
measuring
alternating
current.
They
are
particularly
useful
for
measuring
whole
building
electricity
consumption
(or
generation
for
that
matter).
The
split
core
type
such
as
the
SCT-013-000
CT
in
the
picture,
is
particularly
suitable
for
DIY
use
it
can
be
clipped
straight
on
to
either
the
live
or
neutral
wire
coming
into
the
building
without
having
to
do
any
high
voltage
electrical
work.
Like
any
other
transformer,
a
current
transformer
has
a
primary
winding,
a
magnetic
core,
and
a
secondary
winding.
In
the
case
of
whole
building
monitoring
the
primary
is
the
live
or
the
neutral
wire
(not
both)
coming
into
the
building
itself
and
goes
through
the
hole
in
the
CT.
The
secondary
winding
comprises
many
turns
of
fine
wire
housed
within
the
casing
of
the
transformer.
