Basics of Power Distribution System Design
- Single line diagrams
- Distribution system designs
- Fault levels
- System grounding
On the first day, participants will be introduced to single line diagrams and electrical symbols used for distribution equipment, both International Electrotechnical Commission (IEC) and National Electrical Code (NEC) symbols will be covered. Attendees will learn the advantages and disadvantages of different layouts of high 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 distribution system groundings will be covered. Participants will learn about how emergency and critical power systems are integrated with the distribution system.
Power Distribution Equipment
- Metal clad switchgear
- Gas insulated switchgear
- Circuit breakers
On this day participants will learn about high voltage switchgear, including layout, rating and features of distribution switchboards. The day will cover circuit breaker technologies including air-break, SF6 and vacuum. Operation of gas insulated switchgear and distribution transformers will also be included.
Power Distribution Safety and Maintenance
- Power fuses and cables
- Safety grounding
- Arc flash safety
- Distribution system maintenance
On day thee participants will be introduced to operation of HV power fuses and construction of HV power cables. 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.
