IEC 61334-4-1:1996

IEC 61334-4-1:1996 defines the reference model for the communication system used in distribution automation with distribution line carrier systems. It is relevant when teams need a structured technical basis for evaluating how data communication protocols are organized across a utility communication environment. IEC 61334-4-1:1996 supports engineering documentation, technical review, and conformity assessment activities where a clear communication-system model is needed before implementation, testing, or procurement decisions are made.

What is IEC 61334-4-1:1996?

This document sets out the reference model for the communication system within the series Distribution automation using distribution line carrier systems - Part 4: Data communication protocols - Section 1: Reference model of the communication system. It is best understood as a foundational architecture reference rather than a device-specific specification. For engineers and compliance teams, it can help frame how communication functions are categorized and assessed during technical validation, integration planning, and documented evaluation of distribution automation solutions.

Applications of IEC 61334-4-1:1996

IEC 61334-4-1:1996 is typically used in utility automation projects that rely on distribution line carrier communication for data exchange in power distribution networks. It may support protocol analysis, system architecture reviews, procurement specifications, and laboratory evaluation of communication-related functions. Organizations working on control, monitoring, or remote data transmission in electrical distribution systems can use it as a reference point when aligning engineering documentation, testing workflows, and compliance preparation for carrier-based automation schemes.

Why is IEC 61334-4-1:1996 important?

By defining a communication-system reference model, IEC 61334-4-1:1996 helps create a common technical basis for interoperability, verification activities, and operational consistency. That can reduce risk during system integration and improve confidence in conformity assessment preparation, especially when multiple suppliers or subsystem interfaces are involved. It is also useful in procurement and quality workflows because it gives reviewers a clearer basis for comparing technical solutions and checking whether a proposed design aligns with the intended data communication structure.
