Inspection Details

Select the equipment being tested.
Record equipment tag number, feeder ID, or cable circuit identifier.
Record the physical location or room where the test was performed.
Record when the insulation resistance test was performed.
Select the reason for the test.

Safety and Test Preconditions

Confirm the equipment is isolated, de-energized, and locked out/tagged out before testing.
Confirm absence of voltage using an approved meter before connecting the Megger.
Inspect the insulation tester, leads, clips, and probes for damage, contamination, or loose connections.
Confirm the test area is controlled so unauthorized personnel cannot contact exposed conductors.
Verify required PPE is worn per site electrical safety procedure and task hazard assessment.

Environmental and Test Conditions

Record ambient air temperature at the test location.
Record the measured or estimated insulation temperature used for correction.
Record humidity if available, as it may affect interpretation of results.
Select the observed condition of the insulation before testing.
Enter the factor used to correct insulation resistance to the reference temperature.

Insulation Resistance Test Results

Record the DC test voltage applied by the insulation resistance tester.
Record the insulation resistance reading at one minute.
Record the insulation resistance reading at ten minutes.
Calculate PI as ten-minute reading divided by one-minute reading.
Record the corrected insulation resistance value at the reference temperature.

Acceptance, Deficiencies, and Closeout

Confirm the readings meet the project, OEM, or IEEE 43-based acceptance criteria used for this asset.
Select any deficiencies observed during the test or review.
Describe corrective action taken or recommended follow-up, including retest, drying, cleaning, or repair.
Inspector sign-off confirming the test record is complete and accurate.
