IEEE 484-1987 pdf free.IEEE Recommended Practice for Installation Design and Installation ofLarge Lead Storage Batteries for Generating Stations and Substations.
IEEE 484 Considerations that should be included in thedesign of the battery installation depend uponthe requirements or function of the system ofwhich the battery is a part.
General (All Installations).The followingare the general installation design criteria forall large generating station and substation batteries,including Class 1E batteries for nuclearpower generating stations.
(1) Space and floor supports allocated for thebattery and associated equipment should allowfor present and future needs.
(2)The location should be as free from vibration as practical.
(3)The area selected should be clean, dry, wellventilated (see 5.1.4),and provide aisle spacefor inspection, maintenance, testing, and cell replacement. Space should also be provided abovethe cells to allow for operation of lifting equipment,addition of water,and taking measurements (for example, temperature,specific grav-ity,etc).
(4) The optimum cell electrolyte temperature77F(25 C), is the basis for rated performance.A location where this temperature can be maintained will contribute to optimum battery life,performance, and cost of operation. Extreme ambient temperatures should be avoided becauselow temperatures decrease battery capacitywhile prolonged high temperatures shorten battery life.
(5) The location or arrangement should resultin no greater than a 5 F(3 C) temperature dif-ferential between cells at a given time. Localizedheat sources such as direct sunlight,radiators,steam pipes,and space heaters should beavoided.
(6)Portable or stationary water facilitiesshould be provided for rinsing spilled electrolyte.Provisions for neutralizing, containing, or safelydispersing spillage should be included.
(7) The charger and main power distributioncenter should be as close as practical to the battery, consistent with 5.1.1 (9).
(8) Illumination in the battery area shouldequal or exceed the interior lighting recommendations in the Illuminating Engineering SocietyLighting Handbook,1981 Application Volume[11], Fig.2-2.
(9) Nearby equipment with arcing contactsshall be located in such a manner as to avoidthose areas where hydrogen pockets could form. Mounting(1) The most common practice is to mountcells on a steel rack with acidresistant insulation between the cells and the steel of the rack.Metal racks,if used, shall be connected solidlyto the station grounding system. The cells mayalso be mounted on insulated supports securedto a floor or base; the insulation used should berated for full battery voltage. For seismic requirements refer to 5.2.2(4) and (5).IEEE 484 pdf download.
