The useful life of a selected capacitor under operating conditions other than those indicated in the data sheets can be determined by consulting the "AlCap Useful Life Calculation" design tool on our website, or by the use of the respective useful life graph, if such a graph is published in this data book for the requested series.
For this purpose, the rated voltage is applied to the capacitors via a series resistance of approxi-mately 100 for VR 100 V DC, or 1000 for VR >100 V DC, for a period of one hour. Subsequently, the capacitors are stored under no-voltage conditions for 12 to 48 hours at a tem-perature between 15 and 35 °C.
The series capacitor units and banks are usually intended for high-voltage power systems. This standard is applicable to the complete voltage range. This standard does not apply to capacitors of the self-healing metallized dielectric type. The following capacitors, even if connected in series with a circuit, are excluded from this standard:
A minimized tolerance (±0.35 mm) of the overall length l1 of the capacitor (figure 16) avoids un-wanted mechanical forces on the terminals, especially when several capacitors are mounted be-tween heat sink and bus bar. A case with an extra groove near the base for ring-clamp mounting (recommended accessory B44030A0165B ... A0190B).
The international standard for aluminum electrolytic capacitors is IEC 60384-4. The sectional specification mentioned above is complemented by a set of detail specifications that applies to specific design types (e.g. electrolytic capacitors with axial wire leads).
IEC 60384-4 specifies the following maximum values: These values apply to capacitors with a maximum charge of 100000 μC. Proportionally higher dis-sipation factors are permissible for capacitors with higher charge values. Different values and fre-quencies than those stated in the table above are possible for individual series.
IEC 60143-1:2015
IEC 60143-1:2015 applies both to capacitor units and capacitor banks intended to be used connected in series with an a.c. transmission or distribution line or circuit forming part of an a.c. power system having a frequency of 15 Hz to 60 Hz. The primary focus of this standard is on transmission application. The series capacitor units and banks ...
