Distribution Data e-Handbook

Distribution engineers and technicians frequently use "paper" handbooks to find vital engineering information or as references for obtaining simple calculated values. Necessary data is often distributed between various handbooks, with no one handbook providing all the information needed for a particular calculation or task. Also, many of the data handbooks presently in use have not been updated in many years and contain obsolete data. Finding the appropriate information in large set of “paper” handbooks is often time consuming. DSTAR members determined that a searchable and interactive electronic handbook representing the compilation of several different handbooks and data sources could help to improve the efficiency of engineering personnel.


The goal of the DSTAR Data e-Handbook is to create a dynamic electronic document that consists of information commonly used by the DSTAR membership. Covering a variety of distribution engineering topics, the DSTAR e-Handbook is intended to be an authoritative source of information. The material included in the e-Handbook has been obtained from existing distribution handbooks, manufacturer information, standards documents, results from DSTAR software programs, and surveys of the DSTAR membership. All the information has been collated and sanitized for applicability and accuracy.

The e-Handbook is designed to be a living document that is easy to maintain and add to. A common electronic format was chosen because it offers a high level of flexibility to support future document modifications.

The document contains numerous charts and tables with conductor physical and electrical characteristics, motor parameters, transformer and meter connections, reliability data, equipment ratings, protection settings, construction clearances and much more.

A key feature of the e-Handbook is JavaScript-based engineering calculators that are embedded in the PDF document. The document contains 35 such calculators for computations such as voltage drop, short circuit, conductor sag and tension, arc flash hazard, economic analysis and many others.
