• As the parasitic currents flow via the ground connection of the installation,
the sum of the input currents into the filter is no longer equal to zero. A
specific magnitude of the parasitic current can lead to a saturation of the
common-mode choke in the EMC filter and consequently exceed the
permissible interference level. The interference voltage should therefore
be measured on the installed equipment.
• The parasitic currents also flow to the interference source via the filter
housing and the capacitors connected in the filter! Impermissibly high
currents can overload the capacitors and thus endanger the equipment!
