    Low Voltage Distribution Systems and Equipment

    Properly designed, operated and maintained electrical distribution system is a vital element in safety and reliability of an electrical system in an industrial plant.

    This course has been designed to provide participants with an understanding of the layout of low voltage (<1000V) distribution systems found in a typical industrial plant. Topics covered include basic distribution system designs, typical equipment used, and basic maintenance of those equipment and safety issues associated with low voltage distribution system.

    Upon completion of this course, participants will gain an understanding of low voltage distribution system technology within the oil and gas industry.  Having this knowledge will help each technician develop confidence and professional enthusiasm, therefore, increasing their efficiency. The knowledge that technicians gained from this course will be further expanded by on-job training and practical experience they will receive throughout the duration of their career.

    Day 1

    Basics of Low Voltage (LV)  Distribution System

    • Single line diagrams
    • Layout of various distribution systems
    • Stress due to short circuits
    • System grounding 

    On the first day of this course participants will be introduced to single line diagrams and electrical symbols used for distribution equipment, International Electrotechnical Commission (IEC) and National Electrical Code (NEC) symbols will be included.  They will learn the advantages and disadvantages of different layouts of low voltage distribution systems.  Basic fault calculations and the importance of fault levels in the selection of equipment will be explained.  Pros and cons of various low voltage system groundings will also be covered on this day.

    Day 2

    Power Distribution Equipment  

    • Metal clad switchgear
    • Circuit breakers
    • Automatic transfer switches
    • Transformers

    On this day, the participants will learn about low voltage switchgear, including layout, rating and features of distribution switchboards.  The course will cover circuit breaker technologies including air-break and vacuum.  Operation of automatic transfer switches and distribution transformers will also be included.

    Day 3

    Power Distribution Safety and Maintenance

    • LV Fuses and cables
    • Safety grounding
    • Arc flash safety
    • Distribution system maintenance

    On day three, participants will be introduced to operation of LV power fuses and construction of power cables and bus-ducts. Typical safety considerations such as grounding, lightening protection, shock protection and arc flash safety to NFPA 70E will be explained.  Basic maintenance requirements for switchgear, circuit breakers, transformers and cable systems will also be covered.

    This course is designed for electrical technicians, maintenance planners, and supervisors with operation and maintenance responsibilities who work in an industrial plant.

    Anyone taking this course should familiar with electrical installations in an industrial setting.
