ELECTRICAL POWER SYSTEMS BASES I

A.C. SOURCES. D.C. SOURCES. and ONSITE POWER DISTRIBUTION (Continued) l The operational requirement to energize the instrument busses from their associated inverters connected to its associated D.C. bus is satisfied only l
when the inverter's output is from the regulated portion of the inverter and not from the unregulated bypass source via the internal static switch. The associated inverter is either the dedicated inverter for the instrument bus (protection channel or vital bus) or the installed spare inverter for that train. The design configuration allows the spare inverter to be manually
{
aligned to substitute for any of the four (two protection channel and two i
vital bus) inverters for the train.
Interlocks and procedural controls ensure that the spare inverter feeds the loads of only one inverter at a time and that the power source for the spare inverter is the same as the inverter whose loads are being fed by the spare inverter. Additionally, the associated inverters have ratings suitable to support the maximum load of any of the protection channels or the vital busses.
Verifying average electrolyte temperature above the minimum for which the battery was sized, tctal battery terminal voltage on float charge, connection resistance values, and the performance of battery service and discharge tests ensures the effectiveness of the charging system, the ability to handle high discharge rates, and compares the battery capacity at that time with the rated j
capacity.
Table 4.8-2 specifies the normal limits for each designated pilot cell and each connected cell for electrolyte level, float voltage, and specific
)
gravity. The limits for the designated pilot cells float voltage and specific gravity, greater than 2.13 volts and 0.015 below the manufacturer's full charge specific gravity or a battery charger current that had stabilized at a low value, is characteristic of a charged cell with adequate capacity. The normal limits for each connected cell for float voltage and specific gravity, l
greater than 2.13 volts and not more than 0.020 below the manufacturer's full charge specific gravity with an average specific gravity of all the connected cells not more than 0.010 below the manufacturer's full charge specific 4
gravity, ensures the OPERABILITY and capability of the battery.
