About This Item
IEC 62351-6:2020 addresses data and communications security for IEC 61850 environments, making it a relevant technical reference for organizations that need to evaluate protection of power system communications. For engineers, testers, and compliance teams, it supports structured review of security-related requirements within substation and automation communication workflows. IEC 62351-6:2020 is typically used when assessing whether implementation, verification activities, and technical documentation align with secure operational expectations for electrical power systems and associated information exchange.
Purpose of IEC 62351-6:2020
The purpose of IEC 62351-6:2020 is to define security considerations for IEC 61850-based communications, helping reduce exposure to unauthorized access, message tampering, and other risks in digitally connected power system applications. It is most useful as a technical document for design review, conformity assessment, and compliance preparation where secure interoperability matters. Organizations may use it to support engineering specification development, documented evaluation, and technical validation of communication arrangements in automation and control environments.
Compliance applications of IEC 62351-6:2020
IEC 62351-6:2020 is relevant in procurement, laboratory evaluation, and system acceptance workflows for utilities, substation automation projects, and related electrical equipment deployments that rely on IEC 61850 communications. It can support technical assessment during specification review, factory testing, site verification, and operational readiness checks. Compliance teams often use it as a reference point when preparing evidence for conformity assessment, particularly where security controls must be considered alongside interoperability and operational consistency.
Benefits of IEC 62351-6:2020
Using IEC 62351-6:2020 can improve risk management by giving project teams a clearer basis for evaluating secure communication practices in power system automation. It supports more consistent testing workflows, stronger engineering documentation, and better alignment between design intent and verification activities. For procurement and compliance functions, it can help reduce ambiguity during product evaluation and technical review, while also supporting safety-oriented decision-making and quality assurance across connected electrical systems.
