Rise of Earth Potential (RoEP) Know the Risks
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 […]
Earthing Calculations for Safe System Design
Earthing Calculations regarding your safety – you’re overdue an update! If 1-ohm is still in circulation on your documentation then this section applies to you. Even though the Earthing Calculations for determining a safe System Earth (Ground) has shifted away from an arbitrary resistance figure, usually <1 ohm. It’s still all too common to see […]
Reducing the Risk of Step and Touch Potential
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: […]
Employ a CDEGS Certified User to Avoid Wrong Trousers Mishap
CDEGS Certified User – The Right Trousers CDEGS – The Misconception The term ‘CDEGS’ is loosely banded around a lot in our sector. To deliver safe Electrical Earthing System Design. When carrying out earth potential rise studies. Therefore, the trouble is there’s a lot of confusion. Also, misinformation surrounding which version of CDEGS should be used. […]
