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.
