6.3 OUTPUT DISTRIBUTION
As the output of the SRF is considered to be a "clean filtered
" supply it should not be subjected to situations where further
transients can be introduced. The "clean " supply should
not be run external to the facility, ie to provide power to an
external building or tower lighting. From the aspect of transient
protection to do so would create possible points of entry for
transient energy to the protected zone.
A similar scenario exists where the output of the SRF is fed
to an electrically "noisy " load. Any transients developed by this
load may also be fed to other equipment connected to the
same supply.
Electrically noisy equipment should ideally be supplied from
a separate SRF and all cabling should be run in isolation
to other cables.
