Earthing System Design Procedure A Probabilistic Approach

Earthing System Design A Probabilistic Approach

What are the procedures for creating an HV Earthing System Design? Also, how might these differ from an LV Earth design? Firstly, although the principles underpinning HV and LV earthing are similar, the approaches are very different. Probabilistic Approach The first huge difference is the recognition that HV electrical earthing design is probabilistic in nature. […]

Rise of Earth Potential (RoEP) Know the Risks

Rise of Earth Potential Risk Site - Sub Station

Awareness of step and touch potential, caused by a rise of earth potential. Is essential for anyone working on high-voltage power transmission and distribution systems above 1 kV. A rise of earth potential A rise of earth potential is caused by electrical faults that occur at electrical substations. Power plants, or high-voltage transmission lines. Therefore, short-circuit […]

Reducing the Risk of Step and Touch Potential

touch potential voltage

Awareness of step potential and touch potential risks, caused by an earth potential rise. Is vital for anyone working on high-voltage power transmission. Also, distribution systems above 1 kV. Earth Potential Rise Earth potential rise (EPR) is caused by an imbalance of electrical charges between the earth and an electrical system, it can occur at: […]
