Integrity and Through-Life-Degradation of Electrical Wiring, Connectors and Components Using Long-term IFD, Lincoln
The reliability, availability and the robustness of electrical and electronic systems are significantly affected by the degradation of cabling, insulation and connector components, with their deterioration being typically monitored through use of visual inspection or high potential testing. However, the detection of emerging intermittent and integrity faults in Electrical Wiring Interconnection Systems (EWIS), which can transiently disturb (possibly safety critical) system operation, and which constitute a high proportion of no‐fault‐found (NFF) cases encountered in practice, remain particularly difficult.
In collaboration with industry, who have agreed to provide access to a prototype analysis system, the feasibility study will explore how the current generation of Intermittent Fault Detection (IFD) tools can be used to obtain an assessment of the long‐term integrity of Electrical Wiring Interconnection Systems (EWIS) and of candidate electrical machine and associated power electronic component/inverter technologies. In so doing, the work will present results on the first scoping studies to broaden the current applicability of these tools and provide and report on the possible merits of extending the underlying concepts to address the more challenging issues of enhanced diagnostics and prognostics.
