Program Overview
Most engineers learn low-voltage and high-voltage systems separately, yet in a real facility they operate as one network: utility supply, HV switchgear, transformers, LV distribution and on-site generation. Faults and unsafe practices at one level propagate to the other. This program treats the system as a whole.
Participants begin with the dangers of electricity and the regulatory framework, then progress through permit-to-work and safe isolation, distribution system design, earthing arrangements and fault behavior. Protective relaying, generator synchronization and HV switchgear operation complete the picture. The course uses IEC 60364 for LV installations, IEC 61936-1 for installations above 1 kV, the IEEE C37 series for switchgear and protection, and NFPA 70E for safe work, so participants can work confidently in facilities designed to either US or international practice.
Learning Outcomes

Assessment & Certification
Assessment combines a written examination on LV and HV system design, protection, earthing and safe operation with a practical assessment in which each participant carries out a permit-controlled isolation on HV switchgear and completes a generator synchronization exercise on a training rig or simulator. Practical sessions take place at ASEEE-approved training centers, using calibrated equipment and realistic work scenarios under the supervision of a qualified assessor.
Participants who meet the competency criteria receive an ASEEE competency certificate carrying a unique certificate ID that employers and clients can verify online through Certificate Check. ASEEE recommends recertification every 3 years to keep skills aligned with current practice and revised standards.
