The cyclic permutation of longitudinal sheath connections results in similar sheath over voltage problems at points where the subdivided sheaths are insulated as in single grounded cable sheath.
Therefore, these insulated points will have to be provided with suitable over voltage protection (surge arrestors, non-linear silicon-carbide or zinc oxide resistors)
Mixed System: Sometimes mixed system Le., cross-bonding and single point bonding in the same circuit can be used where the number of minor sections cannot be divided over 3 such as
4 or 5 sections. Here cross-bonding system can be considered for the first 3 sections and single point bonding used for the other section(s).
TECHNICAL DETAILS
Cable losses can be divided as current dependent and voltage dependent. |
High voltage surge arresters, also called lightning arresters, are electrical devices designed to protect high voltage systems and equipment from voltage surges or transients caused by lightning strikes, switching operations, or other sources. They are typically installed in ...
