🎯 Course Description:
This 5-day foundational-to-intermediate course provides participants with a practical and theoretical understanding of electrical power distribution systems—from substations to final load points. The course covers the design, components, operation, maintenance, and troubleshooting of low and medium-voltage distribution networks, based on international standards like IEC, IEEE, NEC, and NFPA 70.
Participants will explore system configurations (radial, loop, and network), key equipment (transformers, switchgear, busbars, circuit breakers, feeders), and learn how to apply preventive maintenance, use diagnostic tools, and execute safe and systematic fault-finding procedures.
👥 Who Should Attend:
-
Electrical maintenance and utility technicians
-
Power system engineers and supervisors
-
Facility and plant maintenance personnel
-
Industrial electricians
-
