3.5.1
Test Conditions
3.5.1.1
Data
Measurements shall be made and recorded of parameters necessary to verify
that each set meets specified parameters. If the results of any test step
are not satisfactory, adjustments or replacements shall be made and the
step repeated until satisfactory results are obtained. Unless otherwise
indicated, data shall be taken during engine-generator set operation and
recorded in 15 minute intervals and shall include: readings of
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. In the following tests where measurements are to be recorded after
stabilization of an engine-generator set parameter (voltage, frequency,
current, temperature, etc.), stabilization is considered to have occurred
when measurements are maintained within the specified bandwidths or
tolerances, for a minimum of four consecutive readings. Electrical
measurements shall be performed in accordance with IEEE Std 120.
Definitions and terms are in accordance with IEEE Std 100. Temperature
limits in the rating of electrical equipment and for the evaluation of
electrical insulation shall be in accordance with IEEE Std 1.
3.5.1.2
Power Factor
Engine-generator set operating tests shall be made utilizing a load with
[the power factor specified in the engine generator set parameter schedule]
[a [_____] power factor].
3.5.1.3
Contractor Supplied Items
The Contractor shall provide all 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 under
this specification shall be verified during test runs by test instruments
of precision and accuracy greater than the tested items. Test instrument
accuracy shall be at least as follows: current, 1.5%; voltage, 1.5%; real
power, 1.5%; reactive power, 1.5%; power factor, 3%; frequency, 0.5%. Test
instruments shall be calibrated by a recognized standards laboratory within
[30] [90] days prior to testing.
3.5.1.5
Sequence
The sequence of testing shall be as specified in the approved testing plan
unless variance in 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; Safety run Tests; and Performance Tests and Final
Inspection.
