This guidance provides for the protection of stationary battery systems, which include the battery and DC components to and including the first protective device downstream of battery terminals. Recommendations are not intended to set requirements; rather, they present options to the battery system designer concerning the types of protection available.
Abstract: Sets out recommended practices for the installation, maintenance, testing and replacement of vented secondary batteries permanently installed in buildings.
Scope:
This Standard sets out recommended practices for the installation, maintenance, testing and replacement of vented secondary batteries permanently installed in or on buildings. It also provides guidance to determine when batteries should be replaced.
The document provides alternative approaches and practices for design, operation, maintenance, integration and interoperability, including distributed resources interconnection, of stationary or mobile battery energy storage systems (BESS) with the EPS at customer facilities, electricity distribution facilities or bulk transmission electricity facilities.
The guide covers outdoor ac substations, either conventional or gas-insulated. Distribution, transmission, and generating plant substations are also included. With proper caution, the methods described herein are also applicable to indoor portions of such substations, or to sub-stations that are wholly indoors. No attempt is made to cover the grounding problems peculiar to DC substations. A quantitative analysis of the effects of lightning surges is also beyond the scope of this guide.
The original guide (1994) was developed to identify substation fire protection practices that generally have been accepted by industry. The new edition includes changes in industry practices for substation fire protection. New clauses on fire hazard assessment and pre-fire planning have been added. The purpose of the original guide (1994) was to give design guidance, fire hazard assessment, and pre-fire planning in the area of fire protection to substation engineers.
