IEEE C37.118.2-2011

IEEE C37.118.2-2011 is a technical standard for synchrophasor data transfer in power systems, defining how measurement data is communicated between devices and applications. It is relevant to power, energy, and industry applications where synchronized phasor information must move reliably across monitoring and control environments. By setting a common framework for data exchange, IEEE C37.118.2-2011 helps support consistent integration, more dependable system visibility, and clearer engineering expectations for data handling.

Overview of IEEE C37.118.2-2011

This standard addresses the communication side of synchrophasor systems, with attention to how time-aligned electrical measurements are transferred for use in power-system analysis and operations. IEEE C37.118.2-2011 is associated with environments that depend on precise, synchronized data streams rather than general-purpose messaging. For engineers, integrators, and specifiers, it provides a focused reference for data transfer behavior, helping align equipment and software around a shared technical basis.

Typical use cases

IEEE C37.118.2-2011 is commonly used when synchrophasor data must be carried between measurement units, communications networks, and supervisory applications in electrical power installations. It is relevant to monitoring centers, substation and grid equipment, and system studies that depend on time-synchronized values from field devices. The standard may also be used during product selection and interface planning for equipment that must exchange phasor data in a controlled and interoperable way.

Why it matters

In practice, IEEE C37.118.2-2011 helps reduce ambiguity in how synchrophasor data is transferred, which is important for compliance, testing, and procurement decisions. A clear standard can improve consistency across devices from different manufacturers and lower integration risk in power-system communications. For organizations working with monitoring, control, or analysis functions, using IEEE C37.118.2-2011 can support more predictable performance and better coordination between engineering teams, vendors, and validation processes.
