EXAMPLE OF CHECKING THE SEPARATION AMONG ELECTRICAL CIRCUITS
...and among those
others circuits
…and Earth installation
Between active parts of
the separated circuit...
Insulation or safety transformer making
the separation among the circuits.
EQUALIZING POTENTIAL NODE
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 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.
