This presentation will outline two case studies of testing performed by Safearth. The key topics covered will include what was tested, how it was tested and what was discovered. The key takeaway will be the similarities and the differences in approaching two contrasting installations. The two scenarios covered are:
โข A simple routine earthing system assessment.
โข What is involved? What test methodologies are applicable?
โข What approach should we take?
โข What makes it routine?
โข How often should we be performing these tests?
โข And a more complex incident investigation.
โข What are the reasons for the test?
โข What are the primary causes of the incident?
โข How do we determine the causes? What test methodologies are needed to identify these causes?
โข Can the testing help to determine the remedial requirements or options?
All cases discussed are based on circumstances that occurred. In some cases, actualities have been slightly changed to protect the innocent and illustrate the point more clearly.
