| Aspect | Extra High Voltage Engineer | High Voltage Engineer |
|---|
| Certifications | Professional Engineer (PE), HV-specific training | PE, HV training, safety certifications |
| Work Environment | Design, testing, and maintenance of EHV systems (>345kV) | Design, testing, and maintenance of HV systems (up to 345kV) |
| Industry Usage | Power transmission, large-scale grid projects | Power distribution, substation projects |
Extra High Voltage Engineers focus on systems exceeding 345kV, requiring specialized skills and certifications, while High Voltage Engineers work with systems up to 345kV. Both roles involve designing, testing, and maintaining electrical infrastructure but differ mainly in voltage levels and project scope.
