ARMY TM 9-6115-464-34AIR FORCE TO 35C2-3-445-2NAVY NAVFAC P-8-624-34Section Il. OPERATING TESTS4-6. GENERAL.a. The tests described in this section require generator set operation and provide verification of generatorset performance characteristics.NOTEAll tests shall be conducted with the 240/416 volt connections, unless otherwisespecified. All tests that are applicable, will be conducted on both Mode I and Mode IIgenerator sets. Mode I tests shall be conducted at 60 Hz only unless otherwisespecified.b. Unless otherwise specified, all test instrumentation will be in accordance with Military StandardizationHandbook MIL-HDBK-705 and Military Standard MIL-STD-705.c. Temperatures will be measured by means of appropriately located thermocouples and properly calibratedread out devices. Thermocouples will be insulated from contact with other metals, as practical. Temperatureswill be recorded in degrees Fahrenheit or Centigrade, depending on the instrument scale, but will be convertedto degrees Fahrenheit in all cases. Barometric pressures will be measured by a mercurial barometer which willbe corrected for the temperature of the scale, the mercury, for vapor pressure and for the location of thebarometer with regard to altitude and latitude. Aneroid barometers will not be used.d. Operation procedures required in support of the individual tests specified herein shall be performed as inthe Operator and Unit Maintenance Manual.e. All test results for generator set overhaul, shall be logged on the appropriate forms as required.f. Perform the operating tests as indicated in table 4-1.4-7. DIRECTION OF ROTATION CONTROLS.With the generator set running at a rated load, rotate the following controls and verify their proper operation.a. Frequency Adjust Control. On Class 1 sets clockwise rotation of the frequency adjust control rheostatmust cause set frequency to increase as indicated on the frequency meter. On Class 2 sets counterclockwiserotation of manual speed control must increase frequency.b. Voltage Adjust Control. Clockwise rotation of the voltage adjust control must cause set voltage to increaseas indicated on the voltmeter.c. Governor Paralleling Control (Class 1 Sets Only). Counterclockwise rotation of the governor parallelingcontrol must cause an increase in the signal appearing at the paralleling receptacles.d. Voltage Regulator Paralleling Control. Clockwise rotation of the voltage regulator paralleling control mustcause that set to increase its share of the total reactive Kva.4-8. REVERSE POWER PROTECTIVE DEVICE TESTa. Operate two generator sets in parallel at no load, with contractors closed.b. Lower speed of set being tested until the main contactor opens.c. Record the value on the kilowatt meter of the other set at the moment the contactor opens. The loadcontactor of the set under test must open when power flow into the generator exceeds 20 percent of the ratedvalue.4-2
