Test insulators and bushings of equipment by inducing voltage across insulation, testing current, and calculating insulation loss.

“Test insulators and bushings of equipment by inducing voltage across insulation, testing current, and calculating insulation loss.” is a supplemental task performed by Electrical and Electronics Repairers, Powerhouse, Substation, and Relay. Among the occupation's 16 rated tasks, workers place it 9th by importance (#8 most important). About 60% of workers say it is relevant to their job.

This is a single occupation-specific task statement from O*NET. The figures below describe how central the task is to the job and what independent studies measure about AI and this kind of work — not a prediction that the task will be automated.

Work activities this task rolls up to

O*NET groups concrete tasks into broader work activities shared across many occupations.

• Test performance of equipment or systems. in Inspecting Equipment, Structures, or Materials

AI exposure

The OpenAI / Eloundou “GPTs are GPTs” study rates this task E0. No direct exposure — current language models give little or no time savings on this task.

Exposure measures whether a model could meaningfully speed the task up — it is an estimate of overlap with model capabilities, not a measure of whether the work will be done by software. The study's intermediate score (β) for this task is 0.00. Automation potential label: T0.
