In the AI era: what happens to Power station, substation, and relay electrical maintenance technician
Electrical and electronics engineers face mixed impacts from AI: repetitive tasks like design verification and wiring optimization can be automated, but complex system integration, innovative design, and safety compliance still require human judgment; using AI properly can improve efficiency.
-
Replaces work for electrical engineers in low-voltage control system design: manual drafting of schematics, calculating cable lengths, and generating bill of materials.
↗ Data sources -
Replaced the tasks of electrical engineers in manually solving Maxwell's equations and conducting experimental verification for electromagnetic field calculations, motor design, and thermal analysis.
-
Replaces electrical engineers' work in drawing electrical schematics, generating terminal wiring diagrams, and compiling drawing lists in industrial automation projects.
-
Replaced electronic engineers' manual waveform debugging, test case writing, and logic verification in chip design.
-
It replaces repetitive simulation work in motor design, such as magnetic field analysis, torque calculation, and efficiency evaluation for electrical engineers.
-
Partially replaces electronic engineers' manual routing and signal integrity analysis in PCB layout, reducing design verification time.
