Study of dielectric response in progressive tension-increase tests on stator windings on large rotating machines

Progressive tension-increase tests are one of the diagnostic methods currently used by Hydro-Québec for the stator isolation system on its hydro alternators. This test is part of MIDA, an expert diagnostics toolkit in use at Hydro-Québec. The effect of certain flaws affecting the quality of the signal during the test, especially with regard to the problem of copper-insulation delamination, has yet to be investigated. The research includes laboratory tests and mathematical modelling of current-tension curves in progressive tension-increase tests, which are also the project’s two objectives.
