Abstract:
When a GSE power meter registered zero due to an AC power glitch, the test monitoring and control software interpreted this as a loss of power and increased the test level past the maximum rating of the test article. This ground test error could have damaged flight hardware. Perform FMEA on test equipment to identify all potential GSE-induced failure modes. Either program the test control software or insert a limiting hardware device to prevent overtest.
