ELEC210B DESCRIPTION

This course covers the design of the delivery and protection systems for the distribution of electricity to commercial and industrial customers. It introduces the NEC and the Trinidad and Tobago Electrical Codes, and the special requirements needed for the safe operation of electrical equipment in hazardous locations. It covers the layout, construction, protection, and operation of distribution substations and lines, and lighting systems and motor circuits.

LEARNING OUTCOMES Upon successful completion of this course, the student should be able to: Knowledge and Understanding 1. Understand distribution systems Cognitive skills 1. Apply protection theory to distribution circuits

Practical and Professional skills 1. Design distribution systems 2. Protect distribution systems Transferable and Key skills Apply problem-solving methodologies AREAS OF STUDY

Introduction Utility load classifications, distribution system layout Distribution Equipment Need for distribution transformers, types of distribution transformers, circuit breakers, reclosers, sectionalizers, disconnect switches, fuses, lightning protection, protective relays, metering equipment Distribution Substations Layout selection criteria, substation construction methods, insulation coordination, voltage regulation, substation layout, faults, substation protection, grounding Distribution Line Construction Trinidad and Tobago Electrical Codes, NEC codes, construction specifications and standards, conductor supports, overhead conductors, underground distribution, residential distribution layout, industrial distribution load LEARNING AND TEACHING STRATEGY The unit will be based on lectures, laboratory exercises, a field trip, and a design project evaluated on a practical power system simulator. ASSESSMENT Assessment Element 1

weighting: 20% assessment type: laboratory examination special facilities: laboratory time/duration: 3 hours

Assessment Element 2 weighting: 20% assessment. type: design project report and seminar/field trip report and seminar special facilities: electrical engineering laboratory with presentation display facilities time/duration: end of semester/twenty minutes for groups of not more than 3

Assessment Element 3

weighting: 60% assessment. type: final examination special facilities: examination conditions time/duration: 3 hrs ASSESSMENT STRATEGY The laboratory examination will consist of one of the laboratory exercises performed during the semester. Performance of the laboratory exercises and submission of the laboratory reports are prerequisites for entry to the laboratory examination. No credit will be awarded for the laboratory reports. These will be critiqued and returned before the laboratory examination. The design project and field trip will be evaluated mainly from a presentation and/or demonstration to, and an oral examination by, a panel consisting of, but not limited to, the course lecturer and a senior distribution engineer assigned from the Trinidad and Tobago Electricity Commission. Other than the design project and field trip reports, the submission of which is mandatory and necessary for admission to the presentation and oral examination, no credit will be awarded for assignments. The design project and field trip reports and the assignments will be critiqued and returned before the examination. Participation in the field trip is a prerequisite for submission of the report and entry to the associated examination. Each student must keep a record in a logbook of all work done on the design project. This logbook must be submitted with the design project report. Aggregation and Re-assessment Rules The three assessment elements will be aggregated to obtain one overall course mark. All elements must be passed individually.
