04 Mar 2018 | Besides, the dc-link capacitor bank dominates the lifetime consumption. |
83 Citations | The results showed that the PbO 2 /AC hybrid capacitor exhibited high capacitance, good cycling stability and long cycle life. |
| The results also suggest that the extent of time on watch determines the efficiency of detection—this efficiency being lowest after 16 to 18 hours of continuous watch. | |
27 Citations | Storing and retrieval of optical energy will be useful for developing a magnetically tunable optical capacitor. |
| A case study of a 2-MW wind turbine shows that the lifecycle is significantly reduced from the individual capacitor to the capacitor bank, where the dc-link capacitor bank dominates the lifetime consumption. | |
| The capacitor ageing presents indicators such as a decrease in the capacitance and an increase in the equivalent series resistance, the detection of which can be used for capacitor health monitoring. | |
| The proposed monitoring strategy does not rely on the information of all capacitor voltage and current, which effectively simplifies the algorithm for capacitance estimation. | |
| Also, long cycling did not influence any of the electrochemical properties of this hybrid electrochemical capacitor, which makes it an interesting energy storage device. | |
| Thus, the capacitor deterioration can be diagnosed. | |
| Furthermore, a new capacitor lifetime monitoring technique is proposed, which employs this signal for calculating equivalent series resistance of the capacitor. | |
| The chemistry developed during this study displayed long-term cycling potential and demonstrated the stability of the capacitor for continued usage. | |
60 Citations | These results indicate that the TR-PEN films can be used over a long term as capacitor films at temperatures up to 300 °C. |
| Knowing these two phenomena increase equivalent series resistance (ESR) of the capacitor, tracking ESR value over the system operating time can be a good indicator for state of health of an electrolytic capacitor. | |
01 Jan 2012 134 Citations | The watch system shall be such that the efficiency of watch-keeping officers and watch-keeping ratings is not impaired by fatigue. |
01 Sep 2014 | The result shows that the Film capacitor bank design is the high reliability and the long life solution in each design. |
