IEC 60143-2:2012/AMD1:2021 is a targeted technical reference for series capacitors used in power systems, with a specific focus on protective equipment for series capacitor banks. It is relevant when engineers, utilities, and procurement teams need a reliable compliance reference for reviewing protection concepts, equipment selection, and documentation tied to series capacitor installations. As an amendment to the parent document, IEC 60143-2:2012/AMD1:2021 should be used as a modifying and supporting source within a broader technical assessment and conformity assessment workflow.

Overview of IEC 60143-2:2012/AMD1:2021

This amendment updates the second part of the series on series capacitors for power systems, concentrating on protective equipment associated with series capacitor banks. Its likely purpose is to refine or adjust the technical and compliance expectations that support safe and consistent operation of protective arrangements in high-voltage power applications. For organizations managing engineering documentation, technical review, or acceptance criteria, IEC 60143-2:2012/AMD1:2021 helps keep the parent reference aligned with current evaluation and procurement requirements.

Compliance applications of IEC 60143-2:2012/AMD1:2021

IEC 60143-2:2012/AMD1:2021 is typically used during specification review, equipment procurement, and verification activities for series capacitor bank protective equipment. It may support laboratory evaluation, project documentation, and technical validation for utility transmission assets or related high-voltage installations. In practice, teams may consult it when checking whether protection-related hardware and associated engineering documentation are aligned with the parent series capacitor requirements and internal compliance workflows.

Importance of compliance with IEC 60143-2:2012/AMD1:2021

Using IEC 60143-2:2012/AMD1:2021 in the review process can help reduce technical uncertainty around protection for series capacitor banks and improve consistency across design, testing, and acceptance phases. For organizations involved in safety planning, interoperability checks, or conformity assessment preparation, the amendment supports more structured technical assessment and quality assurance. It can also be useful for procurement teams that need a clear compliance reference before approving equipment for power system applications.

• Supporting reference for protective equipment associated with series capacitor banks
• Useful in technical review of power system series capacitor installations
• Relevant to compliance workflows for specification, verification, and acceptance
• Helps align engineering documentation with the parent document IEC 60143-2:2012
