Summary
Single-point bonding reduces losses in HV cables, but introduces sheath voltage rise. Earth
Read more Read lessContinuity Conductors (ECCs) are used to mitigate this rise, yet their necessity in installations inside substation earthing mats remains unproven. Despite recommendations in CIGRE TB 797, no published studies quantitatively validate the effectiveness of ECCs. Offshore applications, not covered by existing standards, were often managed via solid-bonding schemes, potentially decreasing current carrying capacity or causing overheating. This study addresses the research gap by employing detailed electromagnetic modelling, with all interfence mechanisms involved, to quantify its impact on personnel safety and system integrity in both onshore and offshore installations. Overall, the findings verify that the use of ECCs has insignificant impact on the cable induced voltages and personnel safety in well-grounded HV onshore substations or offshore platforms.
