A method for estimation of insulation residual operation capability of electrical equipment

The reliability of the power semiconductor module on the operating temperature

“…Another approach for predicting the reliability of the power system, based on the physics of failure (POF -Physics of Failure) analysis [22][23][24][25][26][27][28][29]. The reliability of the power system is viewed from its components, taking into account the aging [22] in conjunction with the effect of adverse weather conditions.…”

“…[23] Indicators of reliability of the power system are determined by using a mathematical model of degradation of cable products. [24] Assess the residual life of isolation of electrical devices were obtained [25] on the basis of the generalized polarization index and the experimental data on the change in the intensity of partial discharge in the aging process of the dielectric [26]. Reliability indices of a number of electrical devices are defined taking into account the degradation of the polymer components [27][28][29].…”

Increase resource power electronics module on the physics of failure method

“…For predicting the reliability of power transformers used methods of probabilistic modeling [9], including models based on Markov processes [10]. Another approach for predicting the reliability of the power system, based on the physics of failure (POF -Physics of Failure) analysis [11][12][13][14][15][16][17][18]. The reliability of the power system is viewed from its components, taking into account the aging [11] in conjunction with the effect of adverse weather conditions [12].…”

“…Reliability indices of a number of electrical devices are defined taking into account the degradation of the polymer components [16][17][18]. But the analysis of the physics of failure is usually carried out without taking into account the spatial distribution of temperature change in the time of the objects [11][12][13][14][15][16].…”
