This standard represents a significant update to IEEE 824-1994. Series capacitor bank component and bank duty cycle ratings, equipment insulation levels, protective functions, component testing, instruction books, nameplates, and safety are covered in this standard.
Capacitor standards specify that capacitor units shall give not less than the rated reactive power at rated sinusoidal voltage and frequency, and not more than 110% of this value, measured at 25 °C uniform case and internal temperature.
Selection and calibration of capacitors for use as Standards is a challenging task, especially since the accuracies required, depening on the application, can be very demanding for the test gear as well as for the secondary- and working-standards used.
The recommendations for the capacitor part are given in IEC 60143-1:2004. Specific information about protective equipment can be found in Clause 3 and 10.6. This second edition cancels and replaces the first edition published in 1994 and constitutes a technical revision.
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 good starting point in the design of a capacitor bank is to divide the total phase current, calculated from the desired three-phase kvar rating of the capacitor bank, by the continuous current capability of the capacitor unit to find the minimum number of strings required.

This standard applies to conventional DC capacitors (film foil oil) for HVDC -DC filter applications. This Standard will also be applicable to other applications where the capacitor
Multilayer ceramic capacitors (MLCCs) are known to experience flex cracking when subjected to bending stresses. An experimental study was conducted to determine the susceptibility to flex cracking of flexible-and standard-termination surface mount MLCCs assembled with lead-free or tin-lead solders and aged at two different temperatures for 200 h.
