Jan 2005 - Administratively Withdrawn Safety precautions;
The document provides safety precautions, installation design considerations, and procedures for receiving, storing, commissioning, and maintaining pocket- and fiber-plate Nickel Cadmium storage batteries for PV power systems. Disposal and recycling recommendations are also discussed. This recommended practice applies to all PV power systems, regardless of size or application that contain Nickel Cadmium battery storage subsystems.

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 document provides seismic design recommendations for substations, including qualification of each equipment type. Design recommendations consist of seismic criteria, qualification methods and levels, structural capacities, performance requirements for equipment operation, installation methods, and documentation.

The guide discusses various battery systems so that the user can make informed decisions on selection, installation design, installation, maintenance, and testing of stationary standby batteries used in UPS systems.

The guide describes the structure, application and limitations of the Fire Safety Concepts Tree, which provides an overall structure with which to analyze the potential impact of fire safety strategies. NFPA 550 examines the interrelation of fire safety features and their effect on achieving specific fire safety goals and objectives.

The document outlines fire safety recommendations for gas, oil, coal, and alternative fuel electric generating plants, including high voltage DC converter stations and combustion turbine units used for electric generation. Fire prevention and fire protection recommendations advance the safety of construction and operating personnel, physical integrity of plant components, and the continuity of plant operations.

The document provides fire prevention and fire protection recommendations for hydroelectric generating plants to safeguard personnel, protect physical property, ensure continuity of power production, and control the impact of fire and firefighting activities on the environment. NFPA 851 offers guidance for the design, construction, and operation of hydroelectric facilities. In addition, general plant design, fire protection systems, identification and protection of hazards, and development of a fire risk control program are also covered.

"The standard applies to the classification of degrees of protection provided by enclosures for electrical equipment with a rated voltage not exceeding 72,5 kV. The object of the standard is to give a) Definitions for degrees of protection provided by enclosures of electrical equipment as regards: 1) protection of persons against access to hazardous parts inside the enclosure; 2) protection of the equipment inside the enclosure against ingress of solid foreign objects; 3) protection of the equipment inside the enclosure against harmful effects due to the ingress of water.

This Part of IEC 62485 specifies the basic requirements for secondary batteries and battery installations. The requirements regarding safety, reliability, life expectancy, mechanical strength, cycle stability, internal resistance, and battery temperature, are determined by various applications, and this, in turn, determines the selection of the battery design and technology. In general, the requirements and definitions are specified for Lead-Acid and Nickel Cadmium batteries. For other battery systems with aqueous electrolyte, the requirements may be applied accordingly.
