Bronze Book
The Electric Power Research Institute (EPRI) has developed the 2022 update of the EPRI Underground Distribution Systems Reference Book (Bronze Book). This reference, authored by leading industry expert authors, joins the EPRI series of Power Delivery technical references, commonly known by the color of their covers.
The Bronze Book has been written to be a meaningful reference to utility engineers and personnel involved in the planning, design, manufacture, installation, operation, and maintenance of underground distribution systems. Its development was driven by the impending loss of institutional knowledge through attrition and retirement of experienced resources, and the consequent urgent need to document industry knowledge and practices.
The Bronze Book contains chapter sections that provide information on the state of the industry with respect to underground distribution systems, network and nonnetwork system planning and design, cable ampacity, system protection, civil and electrical construction, underground maintenance and operations including fault location and cable diagnostics, reliability, corrosion, and equipment such as cables, cable accessories, transformers, and capacitors.
The 2023 edition of the EPRI Underground Distribution Systems Reference Book includes a new chapter on “Underground Cable System Quality.”
