IEEE PC37.118.1a/D2, Dec 2013 is an IEEE draft standard focused on synchrophasor measurements for power systems, with an amendment intended to modify selected performance requirements. It is relevant to engineers working with monitoring and measurement functions in power, energy, and industrial applications, where consistent synchrophasor behavior supports more dependable system analysis. For organizations evaluating IEEE PC37.118.1a/D2, Dec 2013, the document helps define expectations for measurement performance, interoperability, and technical alignment in grid-oriented equipment and workflows.

Overview of IEEE PC37.118.1a/D2, Dec 2013

This draft standard addresses synchrophasor measurement requirements within power system environments, building on the technical framework for phasor measurement units and related monitoring functions. The amendment nature of IEEE PC37.118.1a/D2, Dec 2013 indicates a targeted update to selected performance requirements rather than a complete rewrite. That makes it useful where precise measurement behavior, reporting consistency, and testable specifications are important for power network visibility, system studies, and control applications in electrical engineering settings.

Typical use cases

IEEE PC37.118.1a/D2, Dec 2013 is typically consulted when specifying or evaluating synchrophasor-based monitoring equipment, such as phasor measurement units, data concentrators, or grid observability systems. It is relevant in transmission and distribution environments, power system labs, and utility engineering workflows that rely on time-synchronized measurements. The standard may also guide procurement and acceptance testing for equipment used in stability analysis, disturbance monitoring, and performance verification across power and energy applications.

Why it matters

Clear measurement requirements matter because synchrophasor data is often used to support operational decisions and technical analysis in power systems. IEEE PC37.118.1a/D2, Dec 2013 helps define a more consistent basis for compliance, testing, and design control when performance requirements are under review. For buyers and engineers, that can reduce ambiguity during specification comparison, improve confidence in measured results, and support more reliable integration of monitoring devices across components, circuits, devices, and system-level applications.
