Fig 80: HV HRC (current limiting) fuse assembly with fuse
installed
Install test fuse instead of the
Close switch-disconnector.
Trip striker pin of test fuse.
Verify that the striker pin of the test fuse trips the switch-disconnector and that the
switch-disconnector is in the "TRIPPED" position.
Open switch-disconnector.
Verify by control the movement of the switch position indication (see Fig. 5: Switch
position indication, page 12) that the tripping mechanism is charged.
While switching the three-position switch from CLOSED to OPEN position the
switch position indicator changes from TRIPPED to OPEN. This means that the
stored-energized mechanism is pre-charged.
