9 Citations | It is concluded that a low cost flexible synthetic test circuit can be used for developmental testing of vacuum interrupters for capacitor switching duty. |
22 Oct 2018 2 Citations | Experimental results verify that the monitoring method extracts both the ESR and capacitance changes of a capacitor under test. |
41 Citations | This paper presents a new measuring method for comparing different impedances, which allows, for example, the capacitance and the dissipation factor of a capacitor to be determined from the resistance and the time constant of an AC resistor. |
Experimental results verify that the monitoring method obtains both the ESR and capacitance changes of a capacitor under test. | |
15 Oct 2007 147 Citations | It is shown that the proposed method provides a reliable and sensitive indication of capacitor aging without additional hardware requirements for reliable, efficient, and safe operation of the inverter and driven process. |
25 Citations | The “local capacitance” is applicable in cases when the capacitor is measured by a small test signal for various bias voltages. |
Furthermore, a new capacitor lifetime monitoring technique is proposed, which employs this signal for calculating equivalent series resistance of the capacitor. | |
21 Citations | The AC test was easy to use, can be performed by large and small utilities, and is less expensive than current methods. |
07 Apr 2002 | Standard test procedures using continuous AC voltages are very cost intensive due to the high capacitive power demand of the cables and the resulting large sizes of the test sets, whereas other alternative methods do not reproduce similar PD than under service conditions. |
