Course Summary
Industrial electrical networks are essential for the national electricity system to function as efficiently as possible. To ensure these are in a consistent working condition, there are many steps that can be taken to prevent risks and hazards from occurring. Protecting earthing methods are proven to be highly effective at reducing risks and preventing harm to individuals working within the system.
The process of earthing is incredibly important. Those involved must be competent at the type of equipment and tools that are to be used throughout the process. The type of shielding, cabling and the specific practices used can greatly impact the safety and effectiveness of the system. Alongside this equipment, the correct PPE should be used at all times to guarantee personal safety is maintained.
Furthermore, it is crucial to have a strong understanding of external factors such as soil resistance and electrical grid. These will determine the ideal steps to be taken and how to best implement the necessary protective earthing.
During this course, you’ll learn:
To understand the importance of system & protective earthing within an industrial electric network.
To review laws and regulations surrounding the health and safety of earthing systems.
To recognise the consequences of poor protective earthing within an electrical network.
To identify various risks and hazards associated with the electrical earthing process and implement strategies to mitigate them.
To evaluate a range of electrical fault systems and their benefits and limitations.
To assess what tools and equipment can be best utilised for protective earthing.
To analyse the structure, principles and maintenance required of earthing for systems and equipment.
This course is designed for anyone responsible for protective earthing for an industrial electric network. It would be most beneficial for:
Electrical Engineers
Industrial Architects
Risk Managers
HSE Officers
Risk Analysts
Contractors and Sub-Contractors
Construction Managers
This course uses a variety of adult learning styles to aid full understanding and comprehension. Participants will review real-world examples of electrical systems with protective earthing to highlight used equipment, influential factors, and potential safety risks.
Through a combination of various learning methods, including presentations, video materials, practical demonstrations and individual activities, participants will be granted ample opportunities to fully develop their knowledge and skills relating to the course content. The practical activities will also allow them to be assessed by the instructors and receive any constructive feedback for improvement.
