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, for example 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.
