This part of IEC 61881 applies to d.c. electric double-layer capacitors (cell, module and bank) for power electronics intended to be used on rolling stock.

This standard specifies quality requirements and tests, safety requirements, and describes installation and operation information.

NOTE Example of the application for capacitors specified in this Standard; d.c. energy storage, etc.

Capacitors not covered by this Standard:

  • IEC 61881-1: Paper/plastic film capacitors;

  • IEC 61881-2: A luminium electrolytic capaci tors with non-solid electrolyte.

Guidance for installation and operation is given in Clause 9.
