Report

The document describes modern procedures and practices for protecting industrial power distribution systems and associated equipment from damage caused by overvoltages due to lightning, switching, or a system abnormality.

The document describes switchgear as a general term covering switching, interrupting, control, metering, protective, and regulating devices and assemblies of these devices with their associated interconnections, accessories, and supporting structures and provides for the basic operation, protection, inspection, maintenance, and testing of various types of switchgear used in applications of at least 600V.

The document describes the types, operation, and protection of emergency and standby power systems, and provides guidelines for their application. Recommendations are included for the arrangement and protection of fuel supplies feeding emergency and standby power systems.

The document outlines the fundamental conditions necessary for the creation of each hazard. It includes identification and characterization of the possible hazards inherent in the application, use, and abuse of Nickel Cadmium cells and batteries. It also includes examples for appliance design which minimizes these hazards. Additionally it presents some typical but non-exhaustive examples of misuse that may precipitate or actions which mitigate the hazard.

This data sheet covers electrical protection and fire protection for cables and bus bars and discusses aluminum conductors, describing methods of connecting, splicing and terminating to prevent excessive heating that could result in arcing and fire.

This technical report is in development is categorized in: Acid secondary, Alkaline secondary, Cells & batteries.

IEC/TR 62540:2009(E) applies to all stationary lead-acid cells and monobloc batteries for float charge applications (i.e. permanently connected to a load and to a d.c. power supply), in a static location (i.e. not generally intended to be moved from place to place) and incorporated into stationary equipment or installed in battery rooms for use in telecom, uninterruptible power supply (UPS), utility switching, emergency power or similar applications. These batteries are covered by IEC 60896-11, IEC 60896-21 and IEC 60896-22.

This Technical Report covers the opportunity charging of lead-acid traction batteries, i.e. the use of free time during a working period to top up the charge and thus extend the working day of a battery whilst avoiding excessive discharge. The object of this report is to lay down rules or recommendations for the use of opportunity- charging of lead-acid traction batteries of vented and valve-regulated types, when the battery manufacturer has not recommended the required operating procedures.

This is an informative document covering the broadest aspects of automatic monitor systems as they apply to traction battery applications. The subject of the guide covers those monitor characteristics and features which need to be controlled, though not necessarily currently available. In addition it accommodates those characteristics which are measurable and provides interpretations of accuracy and reliability of the information generated. This publication has the status of a Technical Report - type 3
