1.
Set charger float and equalizing voltage levels.
2.
Verify all charger functions and alarms.
3.
Measure each cell voltage and total battery voltage with charger
energized and in float mode of operation.
4.
Perform a capacity load test.
3.5.1.8
Metering and Instrumentation
a.
Visual and Mechanical Inspection
1.
Compare equipment nameplate data with specifications and approved
shop drawings.
2.
Inspect physical and mechanical condition.
3.
Verify tightness of electrical connections.
b.
Electrical Tests
1.
Determine accuracy of meters at 25, 50, 75, and 100 percent of
full scale.
2.
Calibrate watthour meters according to manufacturer's published
data.
3.
Verify all instrument multipliers.
4.
Electrically confirm that current transformer and voltage
transformer secondary circuits are intact.
3.5.1.9
Grounding System
a.
Visual and Mechanical Inspection
1.
Inspect ground system for compliance with contract plans and
specifications.
b.
Electrical Tests
1.
Perform ground-impedance measurements utilizing the
fall-of-potential method. On systems consisting of interconnected
ground rods, perform tests after interconnections are complete.
On systems consisting of a single ground rod perform tests before
any wire is connected. Take measurements in normally dry weather,
not less than 48 hours after rainfall. Use a portable ground
testing megger in accordance with manufacturer's instructions to
test each ground or group of grounds. The instrument shall be
equipped with a meter reading directly in ohms or fractions
thereof to indicate the ground value of the ground rod or
grounding systems under test.
Submit the measured ground resistance of each ground rod and
grounding system, indicating the location of the rod and grounding
system. Include the test method and test setup (i.e., pin
location) used to determine ground resistance and soil conditions
at the time the measurements were made.
