The Sample Protection Philosophy document below is a summary of a sample protection philosophy for non-exporting, inverter-based (NE/I) connections including storage, solar, and wind.
(Note: Other philosophies may also meet the standards.)

Sample Protection Philosophy Document

This document serves as a guide for applicants regarding the kinds of protections, and particularly the categories of protections, that distributors will require for connection.

To form a protection scheme, all the elements for each category within any given protection philosophy are required.

This document is not an approval for connection.

This information should help applicants file complete applications for connection.

An applicant will need to submit detailed protection settings after the utility has completed the impact assessment of the submitted connection application.
