Recommended Practice

The recommended practice document provides recommended design practices and procedures for storage, location, mounting, ventilation, instrumentation, preassembly, assembly, and charging of VLA batteries. Required safety practices are also included. This document is applicable to full-float stationary applications where a battery charger normally maintains the battery fully charged and provides DC loads.

1.1.1 This recommended practice applies to preventive maintenance for electrical, electronic, and communication systems and equipment and is not intended to duplicate or supersede instructions that manufacturers normally provide. Systems and equipment covered are typical of those installed in industrial plants, institutional and commercial buildings, and large multifamily residential complexes. 1.1.2 Consumer appliances and equipment intended primarily for use in the home are not included.

Recommendations and guidance for distributed resources (DR) interconnected on the distribution secondary networks, including both spot networks and grid networks, are provided. This document gives an overview of distribution secondary network systems design, components, and operation; describes considerations for interconnecting DR with networks; and provides potential solutions for the interconnection of DR on network distribution systems. IEEE Std 1547.6-2011 is part of the IEEE 1547™ series of standards.

Background on light flicker caused by fluctuations in power demands of variable loads is presented in this recommended practice. A flicker measurement method is presented using a meter that is completely described in IEC 61000-4-15. The short-term (Pst) and long-term (Plt) flicker indices used for the analysis of flicker data are defined. Flicker limits for various voltage levels are presented. An assessment procedure for evaluating flicker compliance against emission limits is described.

This Recommended Practice encompasses the monitoring of electrical characteristics of single-phase and polyphase ac power systems. It includes consistent descriptions of conducted electromagnetic phenomena occurring on power systems. The document describes nominal conditions and deviations from these nominal conditions that may originate within the source of supply or load equipment, or from interactions between the source and the load. Also, this document discusses power quality monitoring devices, application techniques, and interpretation of monitoring results.

Withdrawn standard. This recommended practice contains application guidelines and procedures for the interconnection and compatible operation of a SWECS with electric utilities. It addresses the interface between the wind system and the utility and the factors relating to equipment protection, power quality, and the safety of operating personnel and the general public.

Withdrawn Standard

The sizing of nickel-cadmium batteries used in standby operation for stationary applications is discussed in this recommended practice

Addresses the inspection of pressure vessels. It includes a description of the various types of pressure vessels and the standards that can be used for their construction and maintenance.
