Cable Accessory Impulse (BIL) Withstand Test

Inspection template for recording basic impulse insulation level (BIL) withstand test results on cable accessories and bushings, including test setup, applied impulse levels, pass/fail outcomes, and any non-conformance against IEEE 386 requirements.

Inspection Details

• Test record ID and date
• Inspector / test technician name
• Specimen identification and asset tag
• Cable accessory or bushing type
• Rated voltage class and BIL rating

Test Setup and Preconditions

• Test equipment calibration current and traceable
• Impulse generator and measuring circuit configured per procedure
• Grounding and bonding verified before test
• Area barricaded and access controlled
• PPE appropriate for high-voltage test task

Environmental and Test Conditions

• Ambient temperature
• Relative humidity
• Specimen surface condition dry and clean
• Test medium and contamination control acceptable

Impulse Withstand Test Results

• Specified impulse withstand level
• Applied positive polarity impulse level
• Applied negative polarity impulse level
• Number of impulses applied per polarity
• No flashover, puncture, or dielectric breakdown observed
• Visible damage, tracking, or insulation deformation present

Acceptance, Non-Conformance, and Closeout

• Result meets IEEE 386 basic impulse insulation level requirement
• Non-conformance or deficiency recorded
• Corrective action or retest required
• Inspector signature
