Análise de Tempo de Quebra de Fluido Isolante sob Alta Voltagem - Modelo Power Weibull

31 Data Insulating Fluid The data in Table 31 illustrate the graphical methods for complete data using the powerWeibull model The data are the times to oil breakdown under high test voltages High voltages quickly yield breakdown data At design voltages time to breakdown runs thousands of years The tests employed two parallel plate electrodes of a certain area and gap The electrical stress is given as a voltage since the electrode geometry was constant The main purpose was to estimate the relationship between time to breakdown and voltage This involves fitting the model to the data The model is used to estimate the probability of product failure during a factory Table 31 Times to Breakdown of an Insulating Fluid 26 kV Min Plotting utes Position 579 163 157952 500 232370 833 28 kV Min Plotting utes Position 6885 100 10829 300 11029 500 42607 700 106760 900 30 kV Min Plotting utes Position 774 45 1705 136 2046 227 2102 318 2266 409 4340 500 4730 591 13907 682 14412 773 17588 864 19490 955 32 kV Min Plotting utes Position 027 33 040 100 069 167 079 233 275 300 391 367 988 433 1395 500 1593 567 2780 633 5324 700 8285 767 8929 833 10058 900 21510 967 34 kV Min Plotting utes Position 019 26 078 79 096 132 131 184 278 237 316 289 415 342 467 395 485 447 650 500 735 553 801 605 827 658 1206 711 3175 763 3252 816 3391 868 3671 921 7289 974 36 kV Min Plotting utes Position 035 33 059 100 096 167 099 233 169 300 197 367 207 433 258 500 271 567 290 633 367 700 399 767 535 833 1377 900 2550 967 38 kV Min Plotting utes Position 009 62 039 187 047 312 073 437 074 562 113 687 140 812 238 937
