Analysis Of The Limitations Of Traditional Power Fitting Testing: The Influence Of Subjective Factors On The Results Of Manual Testing

In the overhead line connectors inspection process, manual judgment still plays a major role. Inspectors' assessments of the appearance, dimensions, and contact surfaces of hardware vary, and different operational experience and skill levels can lead to inconsistent results. Ambient lighting, angles, and operating habits can all affect the accuracy of identifying overhead line hardware defects. Even standardized inspection procedures cannot completely eliminate the influence of operator subjectivity on the results.

Specific Deviations in the Inspection Process

• Dimensional Measurement: When measuring overhead power line connectors using calipers or micrometers, slight deviations may occur due to different reading methods.

• Surface Defect Judgment: The judgment of cracks, corrosion, or scratches relies on visual inspection; fatigue or distraction may cause subtle defects to be missed.

• Mechanical Property Testing: In traditional tensile or compression tests, different force application methods and data reading timing can introduce human error.

These factors combined result in a certain degree of uncertainty in the overhead power line hardware inspection results. Companies relying on manual inspection for quality control need to fully understand the volatility of the results.

Inconsistencies in assessment and record-keeping can lead to discrepancies

Different personnel may arrive at inconsistent assessments of the same batch of power fittings, resulting in inconsistencies in data records. This impacts the reliability of statistical analysis and quality traceability. In the long term, subjective factors may mask potential defects, causing biases in the overall performance evaluation of power fittings.
