An approach to apply the DC network topology protection typically in DC distribution grids is documented in this guide. The intention of this document is to serve as a base specification with an informative annex provided to allow users to modify or develop specific clauses to meet a particular application.

This document provides general guidance on applying direct current (DC) network topology protection in DC distribution grids. Requirements for protection functions, performance, configuration and tests are included. The guide also provides typical application cases and additional conditions for DC network topology protection.

The purpose of this guide is to describe functional requirements for DC network topology protection in DC distribution grids. This guide provides a reference for utilities, integrators, and manufacturers to support improved and more comprehensive specification of DC network topology protection in DC distribution grids.
