System Earthing and Lightning Protection Calculations

System Earthing and Lightning Protection Calculations is designed to provide practical knowledge of electrical earthing and lightning protection systems used in industrial, commercial, and infrastructure projects. The course explains the fundamentals of system earthing, equipment earthing, and protection against electrical faults and lightning surges. Participants learn how to determine earthing requirements based on system voltage, fault current, soil conditions, and installation requirements. It covers soil resistivity, earth electrode selection, earthing conductor sizing, and earth grid design calculations. The course also introduces lightning protection concepts, risk assessment, lightning air terminals, down conductors, and earth termination systems. Practical calculations for earth resistance, touch voltage, step voltage, and conductor sizing are discussed. Participants gain an understanding of surge protection devices and their coordination with earthing and lightning protection systems. The course also covers relevant design considerations, safety requirements, and applicable electrical standards. Emphasis is placed on practical engineering calculations and interpretation of design requirements. By the end of the course, participants can better understand, design, and review earthing and lightning protection systems for engineering projects.
