system components
•selectbased on relevant performance and economic factors wood, steel, and concrete poles and structural components as well as other
components such as distribution transformers and cables
•computeappropriate insulation levels and select insulators, lightning arresters, grounding, and other components that are coordinated to
provide acceptable lightning performance as well as short circuit & overload current levels to adjust and coordinate the protective devices
(fuses & relays) in tandem (series)
•completethe design of an overhead and underground distribution system by applying all of the principles learned in the course

Those who work in the areas of design, construction, operation, maintenance, or safety of electrical overhead and underground distribution systems in a utility or industrial setting need special knowledge and skills for efficient implementation of safe and economical electrical distribution projects. Engineers, technicians, designers, contractors, consultants, line workers, inspectors, safety personnel, supervisors, and others involved with electrical overhead and underground distribution systems will benefit from this course.

This informative course is your opportunity to learn in a short duration of five days all about overhead and underground distribution systems. In this interactive course, you learn about planning and design considerations, overhead conductors, structure types and loading, guying, insulators, insulation and fault protection coordination, grounding, electrical & mechanical characteristics of cables, designs & ratings of distribution transformers, types & characteristics of pad-mounted switchgear, capacitors ratings & types, protection in distribution systems, distribution systems automation and distributed generation.

To gain understanding of overhead and underground distribution systems design, operation and maintenance practices using applicable codes, policies and standards and assimilating the knowledge gained in the course by solving numerical problems.
