Provided by Last Minute Training
Two important topics in power systems engineering will be covered in this two-day course. Power system neutral grounding plays an important role for the safety of personnel, detection of faulted elements, and preservation of power system and equipment. The types/ methods of system neutral grounding used in industrial plants are comprehensively covered in the first part of the course. The second part deals with high-voltage substation ground grid design which is extremely important for the safety of personnel and preservation of equipment. This part of the course covers the soil resistivity measurement, safety requirements, necessary steps for the design of a safe ground grid design and corrective measures.
Objectives
To provide participants with the understanding of:
a Guidelines for the selection of neutral grounding methods for
industrial power systems and power plants
a Safety issues associated with high voltage substation grounding and
step by step approach in the design of a safe grounding system
