Introduction
Electrical safety plays an important role in electrical power systems in maintaining the safety of human beings and equipment. Also, it will maintain the continuity of power supply and power quality to the industrial and commercial consumers. A proper plan, design, and operation of the electrical power system should ensure the safety and reliability of the system. Understanding the steps and procedures employed in a good electrical safety program requires an understanding of the nature of electrical hazards. Understanding the nature of the hazards is useless unless protective strategies are developed to protect the worker. This course includes a synopsis of the types of protective strategies that should be used to protect the worker. This course covers all aspects of safety issues of Electrical power systems including regulatory and environmental requirements, general design considerations, application of switching and power equipment, and safe grounding design.
Objectives
- To present the recommended practices, and guides, of which NFPA 70E contained, which are developed through a consensus standards development process approved by the American National Standards Institute.
- To provide The Safety Standards
- To provide a practical understanding of electrical power system safety.
- To declare the regulatory and legal safety requirements
- To demonstrate the earthing systems Safety and Risk Assessment
- To explain the relationship between maintenance activities for various equipment and safety
- To select and maintain the electrical equipment in hazardous areas and it's standard
- To indicate arc flash hazard and mitigation
- To introduce main recommendations for electrical safety
- To review of general work and plant safety rules
Training Methodology
This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies, and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations. The online course is conducted online using MS-Teams/ClickMeeting.
Who Should Attend?
Electrical power generation systems and distribution engineers and technicians in utilities and industrial plants, managers of private electricity producers and large power consumers, substation engineers, consulting engineers, manufacturers of power equipment and technologists, and other technical personnel involved in the design, operation, and maintenance of high/medium/low voltage power systems.
