5 Operation
5.3 Electrical isolation
The Fusesaver can be used to open
the circuit and de-energize the line after
which another device can be used to
provide electrical isolation.
For example:
• Disconnecting or removing bridges
at the birdguard end to provide
the visible air gap for the applicable
system voltage;
• opening adjacent fuses or isolating
links; and
• opening nearby air break switches.
Electrical isolation
5.4 External lever
The external lever is used by an
operator to change the way a Fusesaver
works for operational reasons such as
live line working. The effect of pulling
the lever down is determined by
configuration (refer KFS-2034 manual
for options).
The effect is in three areas:
• Protection mode
• Manual operation
• SCADA control.
When the lever has changed state, the
LED light blinks ten times in five
seconds to confirm to the operator that
the Fusesaver has recognized the lever
position change.

It is the responsibility of the user to ensure the installation method and
isolation distances achieved comply with local regulations and good
practice.
