INTRODUCTION
This course is designed for students who have prior theoretical knowledge of power
engineering and wish to expand their understanding of the practicalities of electricity
distribution and the factors underpinning them. All Modules reflect contemporary
practice in electricity distribution utilities and are extensively illustrated with both
photographs and diagrams. Each contains a number of questions, many in the form
of design projects, on which the student will receive a marked assessment and
constructive feedback. Students may choose to undertake one or more Modules and
a Certificate of Achievement will be awarded upon satisfactory completion of each
module. However the Certificate of Competence in Electricity Distribution will be
awarded to those completing all six modules.
Modules will be supplied electronically in pdf format, either over the internet or on
CD-ROM dispatched to the student’s home or company address, as preferred.
Students must return questions for assessment within six weeks, after which the
following Module will be dispatched, if the student has elected to undertake more
than one.
COURSE TUTOR
The course tutor enjoyed a long career in a large UK electricity utility, where he
obtained experience at all levels from junior operational engineer through to senior
manager. Over the last ten years he has worked as a consultant overseas and in the
process industries.
