Reliability of electrical insulating systems – statistical approach to empirical endurance models

Reliability of electrical appliances is long term observed parameter. There has been always conflict of interest; however the idea conflict is still sharpening. While end users require reliable operation (especially continuous energy supply), operators of power apparatus face reduction of funds for the repair and maintenance. Managers form their economical point of view try to reduce costs of new assets and operating costs of current assets. This leads to increasing demands on diagnostics and prognostics. As physical, empirical and statistical models are involved, it is possible to predict the behavior of operated assets and though to plan the service activities. The more precise these models are, the more accurate is the prognosis. For prognosis of insulation system reliability, usually…
