IEEE 2819-2022

2819-2022 is a technical standard for voltage overhead power transmission lines operating in parallel mixed with alternating current and direct current. It addresses the electrical and engineering issues that arise when AC and DC transmission systems share a corridor or operate in close proximity, where coupling, insulation, and operating conditions can affect performance. For planners, designers, and utility engineers, this standard helps define a clearer basis for safe, consistent line arrangement and system coordination.

Overview of 2819-2022

This standard focuses on overhead transmission line arrangements where alternating current and direct current lines are mixed in parallel. That technical context makes it relevant to electromagnetic fields, power system interaction, and practical line design choices. As a superseded document, 2819-2022 remains useful for understanding earlier requirements or legacy project references tied to overhead voltage transmission. It is especially relevant where coordination between line configurations, electrical clearances, and operating compatibility must be considered.

Typical use cases

2819-2022 is commonly consulted during transmission corridor planning, route coordination, and the design of overhead lines that combine AC and DC circuits in parallel. It may also support engineering review for conductor arrangement, insulation planning, electromagnetic compatibility checks, and cross-system interference analysis. Utilities, transmission developers, consulting engineers, and maintenance teams can use it when assessing mixed-voltage overhead networks, upgrading existing corridors, or comparing technical requirements for parallel line installations.

Why it matters

In mixed AC and DC overhead transmission environments, design decisions can affect operational stability, interference levels, and overall reliability. 2819-2022 matters because it gives a structured reference for managing those risks and supporting consistent engineering practice. It can help reduce uncertainty in procurement, design review, and compliance work, especially when multiple transmission technologies share the same physical space. For projects involving parallel lines, that consistency is important for safety and long-term performance.
