Qualification methods for Class 1E vented lead acid batteries and racks to be used in nuclear power generating stations outside primary containment are described in this standard. Qualifications required by IEEE Std 308™ can be demonstrated by using the procedures in this standard in accordance with IEEE Std 323™. The application of batteries in nuclear power generating stations can be divided into two sections: duty cycles equal to or less than 8 h and duty cycles greater than 8 h. A process to demonstrate qualifications for both applications is provided in this standard.
This standard establishes uniform procedures for the measurement of electric-field strength, ion-current density, conductivity, monopolar space-charge density and net space-charge density in the vicinity of high-voltage dc (HVDC) sources.
This standard establishes electrical ratings, test procedures and requirements for joints and live front terminations installed on extruded or laminated dielectric shielded power cable systems rated 2.5 kV through 46 kV AC.
This recommended practice covers the voltage endurance testing of form-wound bars and coils for use in large rotating machine stator windings. Such testing is defined for machines with a nominal voltage rating up to 30 000 V. These tests are to be applied at 50 Hz or 60 Hz and may be done at either room temperature or elevated temperature. (Testing at 50 Hz or 60 Hz may yield different times to failure for comparable samples.) The specimen to be tested should be representative of the bars or coils used in the machine, and should include the complete insulated bar…
This guide provides information on selection, sizing, installation design, installation, maintenance, and testing of stationary standby batteries used in uninterruptible power supply (UPS) systems having an ac output. Design requirements of the UPS components are beyond the scope of this document. While this document applies to all UPS systems, it may be impractical to implement some of its guidance and recommendations with small, self-contained systems, such as products intended to back up individual personal computers.
This recommended practice is limited to maintenance, test schedules, and testing procedures that can be used to optimize the life and performance of valve-regulated lead-acid (VRLA) batteries for stationary applications. It also provides guidance to determine when batteries should be replaced. The maintenance and testing programs described in this recommended practice represent "the best program" based on the information reviewed at the time this document was developed. The user should evaluate these practices against their operating experience, operating conditions, manufacturer's recommendations, resources, and needs in developing a maintenance program for a given application. Some guidance is provided to assist the…
Utility battery chargers for stationary battery installations are critical to maximize battery life while supporting the continuous loads on the dc system. This standard is applicable to battery chargers used for stationary applications. It was written to serve as a bridge between the utility application engineer and the charger manufacturer. It describes battery charger operating modes, performance, environmental/mechanical considerations, instrumentation and alarms.
This recommended practice provides specific recommendations for selection and application of parameters for monitoring Valve-Regulated Lead-Acid (VRLA), Vented Lead-Acid (VLA) and Nickel-Cadmium (Ni-Cd) battery systems in stationary applications. The monitoring of battery systems utilizing emerging energy storage technologies (such as lithium, sodium, flow batteries, etc.) are beyond the scope of this recommended practice. This recommended practice also contains several informative annexes. These provide additional tutorial information relating to topics introduced in the body of the document.
