Common use of Substation Grounding Clause in Contracts

Substation Grounding. Both /All parties shall ensure that proper grounding is done at their respective substations. Each sub-station must have a ground mat solidly connected to all metallic structures and other non-energized metallic equipment. The mat shall limit the ground potential gradients to such voltage and current levels that will not endanger the safety of people or damage equipment which are in, or immediately adjacent to, the station under normal and fault conditions. The ground mat size and type shall be based on local soil conditions and available electrical fault current magnitudes. In areas where ground mat voltage rises would not be within acceptable and safe limits (for example due to high soil resistivity or limited sub- station space), grounding rods and ground xxxxx may be used to reduce the ground grid resistance to acceptance levels. Sub-station grounding shall be done in accordance with the norms of the Institute of Electrical and Electronics Engineers (IEEE) – 80.
