Task by task
We graded 15 tasks, listed here from most to least exposed. AI can do 2 of them today, speeds up 6 and leaves 7 to people.
| Task | AI exposure |
|---|---|
| Prepare and maintain records detailing tests, repairs, and maintenance. Record keeping and test logs are routine digital documentation. | 75% AI can do it |
| Maintain inventories of spare parts for all equipment, requisitioning parts as necessary. Inventory tracking and requisition drafting are routine software tasks. | 65% AI can do it |
| Consult manuals, schematics, wiring diagrams, and engineering personnel to troubleshoot and solve equipment problems and to determine optimum equipment functioning. AI can search manuals and schematics and suggest troubleshooting steps. | 50% AI helps |
| Analyze test data to diagnose malfunctions, to determine performance characteristics of systems, or to evaluate effects of system modifications. AI can analyze test data for patterns, but engineers verify diagnoses. | 50% AI helps |
| Notify facility personnel of equipment shutdowns. Shutdown notices can be drafted, but timing and contact are live. | 40% AI helps |
| Schedule and supervise the construction and testing of special devices and the implementation of unique monitoring or control systems. Scheduling can be assisted, but supervision needs in-person leadership. | 35% AI helps |
| Run signal quality and connectivity tests for individual cables, and record results. Cable test hardware runs the tests; software can organize results. | 25% AI helps |
| Schedule and supervise splicing or termination of cables in color-code order. Scheduling assisted by AI; splicing supervision stays physical. | 25% AI helps |
| Inspect and test equipment and circuits to identify malfunctions or defects, using wiring diagrams and testing devices such as ohmmeters, voltmeters, or ammeters. Hands-on electrical testing with meters on live equipment. | 18% Needs a person |
| Test insulators and bushings of equipment by inducing voltage across insulation, testing current, and calculating insulation loss. High-voltage insulation testing is physical; calculations are minor. | 12% Needs a person |

Questions about substation technicians and AI
Will AI replace substation technicians?
Partly. About 3 in 10 working hours go to tasks AI can already do, mostly record keeping and spare parts inventory. Hands-on repair, relay work and high-voltage testing stay with people because they need a person physically at the equipment.
Which substation technician tasks is AI taking over?
Record keeping and parts tracking are the clearest cases. Preparing test logs and repair records scores 75 on exposure, and maintaining spare parts inventories with requisitions scores 65, because both are routine software entries. Searching manuals and schematics for troubleshooting steps scores 50, so AI can suggest fixes that an engineer then checks.
Which substation technician tasks stay human?
Physical high-voltage work stays with technicians. Disconnecting and connecting voltage regulators scores 3 on exposure, and testing insulators and bushings scores 12, because the work needs a person at energized equipment. Testing transformer oil for dielectric strength scores 10 for the same reason.
How can substation technicians stay valuable with AI?
Verify AI output against the equipment itself. Log field results in Megger PowerDB and check them against AutoCAD wiring diagrams before you sign off. Keep the hands-on relay, breaker and oil work strong, since those tasks carry the lowest exposure scores.
