Title:

Insulation coordination for HVAC underground cable systems

Abstracts

Increasing environmental and aesthetic concerns regarding the utilisation of overhead electrical power transmission lines are resulting in a growing need to progress the use of underground alternatives. This increases the importance of looking for opportunities to further reduce the cost ratio between overhead and underground distribution and transmission. One approach is to address the inherent costs associated wtih the cable system by reducing the required withstand capability in line with the actual service requirements rather than traditional levels in particular the transient overvoltage performance.
