The Shuttle Avionics Integration Laboratory, a test bed that simulates Shuttle orbiter systems, was designed with an isolated single-point earth grounding system. A new single power transformer dedicated to the lab area was installed to replace the three existing transformers. This new hardware installation conflicts with the lab's ground isolation requirements but conforms to the National Electrical Code, 1990 edition. A test was conducted to verify that the new single-point, nonisolated lab grounding scheme does not produce an unacceptable electromagnetic environment when compared with the original single-point, isolated grounding scheme.
