I usually only use layers to quickly turn off and on large group items totest out different scenarios or to temporarily turn off poly heavy objects such as trees while I model.
Based on the analysis of AC impedance and two poles voltage test data, the reason of turn - to - turn short circuit fault caused by having copper dregs in generator rotor winding was found.
