Selected Model Engine: C4.4 Generator Frame: LC3034B Genset Rating (kW): 100.0 Line Voltage: 240 Fuel: Diesel Generator Arrangement: 2679912 Genset Rating (kVA): 125.0 Phase Voltage: NA Frequency: 60 Excitation Type: Permanent Magnet Pwr. Factor: 0.8 Rated Current: 300.7 Duty: STANDBY Connection: SERIES DELTA Application: EPG Status: Current General Information Version: 39458 /38397 /39521 /980 GENERATOR INFORMATION (DM7900) ------------------------------------------------------------- 1.Motor Starting Motor starting curves are obtained in accordance with IEC60034, and are displayed at 0.6 power factor.
2.Voltage Dip Prediction of the generator synchronous voltage dip can be made by consulting the plot for the voltage dip value that corresponds to the desired motor starting kVA value. 3.Definitions A)Generator Keys Frame: abbreviation of generator frame size Freq: frequency in hertz. PP/SB: prime/standby duty respectively Volts: line - line terminal voltage kW: rating in electrical kilo watts Model: engine sales model B)Generator Temperature Rise The indicated temperature rises are the IEC/NEMA limits for standby or prime power applications. The quoted rise figures are maximum limits only and are not necessarily indicative of the actual temperature rise of a given machine winding.
C)Centre of Gravity The specified centre of gravity is for the generator only. For single bearing, and two bearing close coupled generators, the center of gra vity is measured from the generator/engine flywheel-housing interface and from the centreline of the rotor Shaft. For two bearing, standalone generators, the center of gravity is measured from the end of the rotor shaft and from the centerline of t he rotor shaft. D)Generator Current Decrement Curves The generator current decrement curve indicates the generator armature current arising from a symmetrical three-phase fault at the generator terminals.
Generators equipped with AREP or PMG excitation systems will sustain 300% of rated armature current for 10 seconds. E)Generator Efficiency Curves The efficiency curve is displayed for the generator only under the given conditions of rating, voltage, frequency and power factor. This is not the overall generating set efficiency curve. 44 3/28/2013 http://tmiwebclassic.cat.com/tmi/servlet/cat.edis.tmiweb.gui.TMIDirector?Action=buildtab... Caterpillar Generator Data Page 8 of 9
