Foot to ground impedance – magic bullet or realistic mitigation measure

If EPR reduction and equipotential grading aren’t practical measures, can high resistivity surfacing materials such as crushed aggregate and bitumen be relied upon to limit electric shock hazards for utility operators and maintenance staff and the public? Is 3kohmm crushed aggregate or 10k ohmm asphalt a realistic assumption for a designer to make? How do […]


What to do when electricity spills out over the suburb?

Utilities in Australia have long been aware of the effect that a substation EPR has on the area surrounding the substation, and their responsibility to look beyond the substation boundary fence and care for people living and working in this region. However, institutional boundaries have sometimes led to conflict or gaps regarding who is responsible […]
