- 3. 0 ' SURVEILLANCE ' REQUIREMENTS 3.7 Emercency Power System Periodic Tests (Continued) i.
Initiation of a simulated auto-start signal to verify that the diesel starts, followed by, ii.
Initiation of a simulated simultaneous loss of 4.16 KV supplies to bus 1A3 (1A4).
Proper operation will be verified by observa-tion of:
(1) De-energization of bus 1A3 (1A4).
(2)
Load shedding from bus (both 4160 V and 480 V).
Ener0 zation of bus 1A3 (1A4).
(3) i (4) Automatic sequence start of emergency load, and (5) Operation of > 5 minutes while its generator is loaded with the emergency load, iii. Verification that emerge g loads do not exceed the 2000-HR KW rating of the' engine, d.
Manual control of diesel generators and breakers shall also be verified during refueling shutdowns, e.
Each diesel generator shall be given a thorough inspection on a refueling (R) frequency in accordance with the manufacturer's recommendations for this class of standby service.-M f.
The futi oil transfer cumps shall be verified to be operable each month.
(2) Station Batttries Every month the voltage of each cell (to the nearest 0.01 a.
volt), the specific gravity, and temperature of a pig) cell in each battery shall be measured and recorded.
b.
Every three months the specific gravity of each cell, the temper-n' ature reading of every fif th cell, and the amount of water added Jg shall be measured and recorded.
During the first refueling
-g n, outage and every third refucling outaq' thereaf ter the battertes shall be subjected to a rated load discharge test.
At monthly intervals the third battery charger, which is c.
capable of being connected to either of the two 0.C. uis-L tribution buses, shall be paralleled in turn to each 0.C.
bus.
In each case, load shall be transf erred to this re-n<
serve battery charger by switching out the normal charger.
The reserve charger shall be run on load for 30 minutes on ocr
$$n.
each bus and the system shall finally be returned to normal.
