Inspection Setup and Safety Controls

Record substation or feeder location, capacitor bank ID, voltage class, and asset tag.
Verify no exposed energized parts, arc-flash boundary issues, standing water, wildlife hazards, or other immediate hazards are present.
Confirm PPE appropriate to the task and site conditions is worn, including electrical PPE as required by the job hazard assessment.
Confirm the capacitor bank is in the correct safe state for the inspection and that any required clearance, switching order, or LOTO is in place.

External Condition of Capacitor Bank

Inspect each visible can for bulging, doming, swelling, or other deformation indicating internal failure.
Check for oil seepage, wet spots, residue, or discoloration on cans, racks, pads, or enclosure surfaces.
Verify fuse links, holders, and associated hardware are intact, properly seated, and free of discoloration, melting, or rupture.
Look for cracks, chips, tracking, contamination, corrosion, or loose terminations on visible insulating components.
Check for bent panels, missing fasteners, loose supports, rust-through, or other enclosure damage.

Controls, Indicators, and Switching Operation

Inspect the control cabinet, seals, door, and gasket condition for evidence of moisture, corrosion, or pest intrusion.
Verify control power is present and that status lights, alarms, or annunciators do not indicate a fault, lockout, or abnormal condition.
Record the observed controller setpoints or operating mode and note whether they match the approved operating plan.
If switching is performed or observed, confirm the capacitor bank energizes and de-energizes without abnormal noise, hesitation, chatter, or failure to operate.
Verify visible switch position, indicator flags, and control indication agree with the actual energized or de-energized condition.

Connections, Grounds, and Housekeeping

Inspect accessible lugs, jumpers, and terminations for looseness, discoloration, arcing marks, or thermal damage.
Verify visible ground leads, bonds, and connections are present, secure, and not damaged or disconnected.
Confirm the immediate area is free of trash, conductive debris, excessive vegetation, and obstructions that could affect access or cooling.

Deficiencies and Follow-Up

List each deficiency, affected component, observed condition, and whether it is critical or requires immediate outage planning.
Select the next action required for the identified deficiency.
Inspector attestation that the inspection was completed accurately.
