IEEE C37.236-2013

IEEE C37.236-2013 is a technical guide for applying protective relays in power systems that use digital communication channels. It addresses how relay functions can be carried over communications-based links, helping engineers think through performance, coordination, and dependable operation in networked protection schemes. As part of the power, energy, and communications interface, the document is relevant where protection depends on both electrical behavior and communication path characteristics.

About IEEE C37.236-2013

This standard focuses on the application of power system protective relays when communication is part of the protection architecture. IEEE C37.236-2013 is useful for understanding how relay-based protection may be implemented, evaluated, and coordinated over digital channels rather than only through direct wiring. It supports engineering decisions where timing, signal transfer, and functional reliability must be considered together. The guide is especially relevant to systems that combine protection, control, and communications in one operating environment.

Where is IEEE C37.236-2013 used?

IEEE C37.236-2013 is typically used in utility and industrial power environments where protective relays communicate across digital networks. That can include substations, transmission and distribution protection schemes, and other installations that rely on remote relay signaling or channel-based coordination. It is also relevant to engineering teams planning relay settings, protection logic, and communication-assisted schemes in systems where dependable message transfer affects trip decisions and fault response.

Importance in practice

In practice, IEEE C37.236-2013 helps reduce uncertainty when protective functions depend on digital communication channels. It can support more consistent design choices, clearer procurement expectations, and better alignment between protection performance and communications capability. For compliance and testing, the guide may help teams verify that relay applications remain dependable under realistic channel conditions. That matters because coordination errors or communication delays can affect fault clearing, system stability, and overall protection integrity.
