IEC 60358-2:2013

IEC 60358-2:2013 defines the technical reference for coupling capacitors and capacitor dividers used as an AC or DC single-phase coupling capacitor connected between line and ground for power line carrier-frequency (PLC) application. It is relevant when teams need a reliable compliance reference for component selection, design review, and test planning in power transmission and communications-related electrical systems. For engineering, procurement, and conformity assessment workflows, IEC 60358-2:2013 helps frame how the equipment category should be evaluated against the intended PLC use case.

What is IEC 60358-2:2013?

This document addresses the application of coupling capacitors and capacitor dividers in a single-phase arrangement connected between line and ground for PLC service. In practical terms, it supports technical validation of equipment intended to couple carrier-frequency signals onto power networks while remaining aligned with the electrical system context described by the title. Engineers and laboratories may use it as a documented evaluation point when reviewing design intent, testing workflows, and compliance preparation for line-to-ground coupling applications.

Applications of IEC 60358-2:2013

IEC 60358-2:2013 is most relevant in power system environments where PLC communication is used for operational signaling, monitoring, or control over electrical infrastructure. It may be consulted during product evaluation, laboratory evaluation, and technical assessment of coupling capacitors or capacitor dividers selected for line-connected service. Procurement teams and compliance specialists can also use it to support specification review, supplier documentation checks, and verification activities tied to high-voltage communication interfaces and related engineering documentation.

Why is IEC 60358-2:2013 important?

Using a clear technical reference for this equipment category helps reduce risk during design validation, acceptance testing, and conformity assessment. It supports consistent interpretation of the intended application, which is important for interoperability, operational consistency, and technical compliance in PLC-related installations. For organizations managing safety, quality assurance, and regulatory preparation, IEC 60358-2:2013 provides a focused basis for comparing products, documenting engineering decisions, and aligning testing standards with procurement and implementation requirements.
