Experimental designs for tracking the influent operating parameters on insulation reliability

Lifetime model of the inverter-fed motors secondary insulation by using a design of experiments

“…The power of this method was proved in different topics such as chemistry, agriculture, electronics, in which numerous parameters must be taken into account together. In electronics, it has been successfully applied to design and optimize industrial applications [14], to control power converters [15], to track relevant parameters on insulating films reliability [16] or to analyze the development of a reliable water-treeing test [17].…”

Electrical ageing modeling of the insulation of low voltage rotating machines fed by inverters with the design of experiments (DoE) method

“…In the domain of electrical insulation degradation, the DoE method has already been used for tracking the influent operating parameters on the insulation lifetime of kapton films [11] and for the degradation analysis in terms of a better understanding of a reliable water-treeing test [12]. In this paper, the DoE method is used to analyze the ageing process of organic rotating machines insulation.…”

“…The first and simplest method is based on a linear relationship between the factors and the logarithm of the lifetime log(L). This approach was previously used for lifetime modeling of kapton films in [11], with a model described by …”

“…This model presents the variation of the logarithm of the lifetime with respect to a logarithmic form of the electrical stress and an exponential form of the temperature, as shown in (11). …”
