6) Power Fuse Inspection
Inspect the condition of all current-limiting
fuses after every fault current condition.
Visually inspect the power fuse blown fuse
indicator (Figure 22, a) or perform continuity
tests to determine the condition of the
fuses. When visually inspecting a fuse, if the
colored indicator on top of the fuse extends
outwards, the fuse is in the OPEN position or
blown. Compare the existing fuse resistance
value to a new fuse value to determine the
condition of the fuse.
Perform continuity tests to determine the
condition of the control power transformer
primary fuses and control power transformer
secondary fuses. Compare the existing
fuse resistance value to a new fuse value
to determine the condition of the fuse. As
required, replace fuses only with new fuses
with the same catalog number, type, voltage
rating, current rating, frequency rating, and
maximum interrupting rating. Refer to the
Operating Instructions label for complete
instructions on fuse replacement. The
operating instructions label is located on the
inside compartment door of the medium
voltage controller.
