Annual Inspection
ATTENTION:
Ensure annual inspections are performed on the
unit. Failure to perform inspections may result in poor equipment
performance, possible damage and/or injury to personnel.
Physical Inspection On an annual basis, harmonic filter units should be physically inspected for
any signs of damage, component breakdown, misadjustment, stress (electrical,
mechanical or thermal) or foreign material. Specifically, check the following:
ATTENTION:
Ensure main power has been disconnected and
locked out before starting the inspection. Verify with a hot stick
or meter that all circuits are voltage-free. Failure to do so may
result in electric shock causing severe burns, injury or death.
Bolts
Check tightness of all bolted power connections with a torque wrench. Set the
wrench to the nominal torque as specified on page 5-1 and apply the set torque
to the connection. Do not tighten beyond the set torque. For inspecting
connections to capacitor terminals, a reduced torque of 10 ft-lb (13.5 N-m)
must be used. Visually inspect all component mounting bolts and tighten any
which are obviously loose.
Structure
Check the cabinet and internal structure for any damage (dents, holes, etc.)
which could reduce electrical clearances or allow direct access to live parts
from outside the cabinet. Repair the damage or order replacement parts as
required.
Cable
Check for cut or worn insulation or damaged lugs due to electromechanical
stress or improper routing (cables will move when subjected to high current).
Replace any damaged cables and re-position any cables that may have moved
from their proper position. Make sure cables do not contact any sharp edges.
