Various methods of passing cables through
the measuring current transformers.
L+ L-
L1 L2 L3
When laying the wires or cables
through the measuring current
transformer, aim for the greatest
possible balance in the centre of the
current transformer and a rectangular
routing for the conductors.
Magnetic alternating fields such as those caused by AC consumers, can influence
the sensitivity of the measuring current transformers. Therefore do not install
devices which produce magnetic fields close to equipment such as transformers,
throttles, or neighbouring conductors with high currents.
Note: always choose the measuring current transformer with the smallest
possible diameter. This will reduce the danger of influences from interference.
