 EXAMPLE OF CHECKING THE SEPARATION AMONG ELECTRICAL CIRCUITS
...And among those
other circuits
...Earth
installation
Between the active
parts of the
separated circuit...
AMPROBE
Measurement of separation among the installation circuits
Insulation or safety transformer making
the separation among the circuits.
Test among the
active parts.
Connect a test
lead
of the
instrument to one
of
the two
conductors of the
separate
circuit
and the other to
one
of the
conductors of a
no
separate
circuit.
Test between
the active parts
and the earth.
Connect a test
lead
of the
instrument to one
of
the two
conductors of the
separate
circuit
and the other to
the
equalising
potential node.
This test is to be
effected only for
SELV circuits or
with
electrical
separation.
