Potentials and profiles around earth electrodes and opposite-side injection for large-area earthing

To determine accurately the extension of hot-zones is crucial in terms of earthing system design and need of mitigation measures. With the wide use of simulation software packages, the credibility of the outcomes has yet to be verified experimentally.

In addition, current testing methods/instruments operate in the range of 10mA to 5A hence the scalability of the measurement (to high fault current) is yet to be established.

Cardiff University had carried out research projects covering the above issues with promising preliminary results. Furthermore, they have acquired necessary site facilities and experience. It is more likely that the above issues will be addressed more efficiently and successfully.

Benefits

This project will be successful if we can understand in greater detail the issues faced around earth electrodes.
