during engine-generator set operation and shall include: readings of all
engine-generator set meters and gauges for electrical and power parameters;
oil pressure; ambient temperature; and engine temperatures available from
meters and gauges supplied as permanent equipment on the engine-generator
set.Electrical measurements shall be performed in accordance with IEEE Std
120. Definitions of terms are in accordance with IEEE Std 100.
Temperature limits in the rating of electrical equipment and for the
evaluation of electrical insulations shall be in accordance with IEEE Std 1.
3.5.1.2
Power Factor
For all engine-generator set operating tests the load power factor shall be
[the power factor specified in the engine-generator set parameter schedule]
[[_____] power factor].
3.5.1.3
Contractor Supplied Items
The Contractor shall provide equipment and supplies required for
inspections and tests including fuel, test instruments, and loadbanks at
the specified power factors.
3.5.1.4
Instruments
Readings of panel gauges, meters, displays, and instruments provided as
permanent equipment shall be verified during test runs, using test
instruments of greater precision and accuracy. Test instrument accuracy
shall be within the following: current plus or minus 1.5%, voltage plus or
minus 1.5%, real power plus or minus 1.5%, reactive power plus or minus
1.5%, power factor plus or minus 3%, frequency plus or minus 0.5%. Test
instruments shall be calibrated by a recognized standards laboratory within
30 days prior to testing.
3.5.1.5
Sequence
The sequence of testing shall be as specified in the approved testing plan
unless variance is authorized by the Contracting Officer. Field testing
shall be performed in the presence of the Contracting Officer. Tests may
be scheduled and sequenced in order to optimize run-time periods; however,
the following general order of testing shall be followed: Construction
Tests; Inspections; Pre-operational Tests; Safety Run Tests; Performance
Tests; and Final Inspection.
3.5.2
Construction Tests
**************************************************************************
NOTE: Coordinate the construction test requirements
with the other specification sections to eliminate
redundant tests and provide additional reference to
necessary tests.
**************************************************************************
Individual component and equipment functional tests for fuel piping,
coolant piping, and lubricating-oil piping, electrical circuit continuity,
insulation resistance, circuit protective devices, and equipment not
provided by the engine-generator set manufacturer shall be performed prior
to connection to the engine-generator set.
