IEEE PC37.238/D6, Feb 2011 is an inactive draft standard profile for using IEEE Std. 1588 Precision Time Protocol in power system applications. It focuses on how synchronized time can support communication and control in utility and industrial power environments, where precise timing affects measurement alignment, event logging, and coordinated operation. This draft is relevant to engineers working with power, networking, and embedded systems that need consistent time distribution across connected equipment.

About IEEE PC37.238/D6, Feb 2011

The document defines a profile for applying IEEE 1588 PTP within power system contexts, helping narrow the protocol to requirements suitable for electrical infrastructure. In practice, a profile such as IEEE PC37.238/D6, Feb 2011 can guide implementers on timing behavior, interoperability expectations, and system coordination needs across devices in substations and related networks. It is intended to support more predictable use of synchronized time in environments where accurate sequence and event correlation are important.

Where is IEEE PC37.238/D6, Feb 2011 used?

IEEE PC37.238/D6, Feb 2011 is mainly relevant in power system communication networks that depend on synchronized clocks, such as substation automation, protection systems, monitoring equipment, and control devices. It may also be used where distributed measurement and event recording must align across multiple units. Because the profile is tied to IEEE 1588, it is especially relevant to networked equipment that exchanges timing information over Ethernet-based infrastructure in utility and industrial power settings.

Importance in practice

Using a clear timing profile helps reduce ambiguity when designing or evaluating synchronized power system networks. IEEE PC37.238/D6, Feb 2011 supports consistency in implementation, which can improve interoperability, testing, and procurement decisions for time-sensitive equipment. For operators and integrators, that kind of control matters when coordinating protection, disturbance recording, and performance verification. Even as an inactive draft, it remains useful for understanding how Precision Time Protocol was being shaped for power applications.
