The standard provides electrical and mechanical requirements for liquid-immersed distribution and power transformers, and autotransformers and regulating transformers; single- and polyphase, with voltages of 601 V or higher in the highest voltage winding, are set forth. It is basis for the establishment of performance, and limited electrical and mechanical interchangeability requirements of equipment are described, and for assistance in the proper selection of such equipment.

The guide was written to provide a relevant PV battery test procedure that can be used to evaluate battery performance and identify appropriate PV battery charging requirements. The document contains a tutorial on Lead-Acid battery technology, battery charging characteristics, and a laboratory test procedure to evaluate charge parameters and battery performance.

The guide is intended to provide assistance to users of stationary battery systems in determining appropriate battery management strategies that may be applied by addressing the primary similarities and differences in battery design and operation for standby versus cycling applications.

The document provides a 3-level system of VRLA String Safety and Performance Criteria based on Telcordia generic requirements documents. The VRLA string criteria levels are defined as follows: ? Level 1, Safety and Minimal Operability – minimum acceptable level of compliance needed to preclude hazards and degradation of the network facility and hazards to personnel, and needed to ensure battery operability at the installation time in controlled environments.

1.1 These requirements cover instrument batteries, enclosed batteries, emergency lighting and power batteries and uninterruptible power supply batteries of the valve regulated or vented type. A battery system composed of vented or valve regulated types with battery management controls and other battery system components, and other chemistries or battery types are covered by the Standard for Batteries for Use in Light Electric Rail (LER) Applications and Stationary Applications, UL 1973.

This Standard provides a method of presenting technical information relating to the selection of storage batteries for photovoltaic systems and to the precision of that information.
Note: A distinguishing feature of photovoltaic (PV) power systems is the unpredictability and limitation on the amount of charging power available and hence on the charge-d ischarge cycles imposed on the storage battery.
1.2
This Standard includes procedures designed to verify the capacity, efficiency, and longevity of storage batteries.

This standard specifies the type, production, and commissioning tests that shall be performed to demonstrate that the interconnection functions and equipment of a distributed resource (DR) conform to IEEE Standard P1547; Interconnection equipment that connects distributed resources (DR) to an electric power system (EPS) must meet the requirements specified in IEEE Standard P1547. Standardized test procedures are necessary to establish and verify compliance with those requirements.

IEEE Std 1547.2-2008 provides application details to support the understanding of IEEE Std 1547-2003 and is intended to serve DR owners and operators as well as area EPS staff. It provides technical background, application details and guidance, requirements rationale, schematics, and examples to facilitate the use of IEEE std 1547-2003. This guide addresses some topics that are related to DR project implementation to enhance user understanding of how IEEE Std 1547-2003 may relate.

This document provides guidelines for monitoring, information exchange, and control for distributed resources (DR) interconnected with electric power systems (EPS)
