After the test the samples are maintained at normal temperature and relative humidity for a period of 4 to 24 hours. When tested after this; 1. The capacitor samples shall be free of cracks, or other mechanical damages and the marking shall remain legible 2. The samples shall meet the original requirement of the Withstanding voltage 3. The samples shall meet the after test requirement of Insulation resistance as furnished in Figure 2 4. The dissipation factor shall be within 2 times the original limits 5. The capacitance change shall not exceed ±5% or ±1 pF LIFE TEST The capacitor samples shall be subjected to a temperature of 125 °C with 150% of rated voltage for 2000 hours. After the test : 1. The capacitor samples shall be free of cracks, or other mechanical damages and the marking shall remain legible 2. The samples shall meet the original requirement of the Withstanding voltage 3. The samples shall meet the original requirements of Insulation resistance as furnished in Figure 1. 4. The dissipation factor shall be within 1.5 times the original limits 5. The capacitance change shall not exceed ±3% or ±1 pF(whichever is greater) for characteristic "C" and ±2.5 ±1pF (whichever is greater) for characteristic D, E and F.) OTHER TYPICAL VARIATION PATTERNS Some typical variation patterns for selected values during heat resistance load life test and moisture proof load life tests as listed below are illustrated in Figures 8 through 10. 1. Insulation resistance Vs. time for heat resistance load life test and moisture proof load life tests (Figure 8). 2. Capacitance change in percentage Vs. time (Figure 9). 3. Dissipation factor Vs. time (Figure 10). Other variation patterns and characteristic for selected values as listed below are furnished as Figures 11 through 14 1. Capacitance change Vs. frequency (Figure 11) 2. Capacitance change Vs. time(Figure 12) 3. Dissipation factor change Vs. frequency(Figure 13) 4. Insulation resistance Vs. temperature (Figure 14) FIGURE 9 FIGURE 10 FIGURE 11 FIGURE 12 FIGURE 13 FIGURE 14 |
