DC CURRENT GENERATOR CHARACTERISTICS PROBLEMS
1 A 150 KW 250 VOLT COMPOUND GENERATOR IS CONNECTED LONGSHUNT IF THE SHUNT FIELD RESISTANCE IS 20 OHMS, WHAT IS THE SERIES FIELD CURRENT AT FULL LOAD?
2 IF THE GENERATOR OF PROBLEM 1 IS CONNECTED SHORT SHUNT,WHAT IS THE FULL LOAD SERIES FIELD CURRENT?
3 A LONG SHUNT COMPOUND GENERATOR HAS A SHUNT FIELD WITH 1200 TURNS PER POLE AND A SERIES FIELD WITH 4 ½ TURNS PER POLE.IF THE SHUNT FIELD AND SERIES FIELD AMPERE TURNS ARE, RESPECTIVELY, 1200 AND 196,CALCULATE THE POWER DELIVERED TO A LOAD WHEN THE TERMINAL VOLTAGE IS 230.
4 A SHORT SHUNT COMPOUND GENERATOR HAS A FULL LOAD CURRENT OF 60 AMP. IF THE SERIES FIELD RESISTANCE IS 0.04 OHM AND A DIVERTER CARRIES 24 AMP,WHAT IS THE DIVERTER RESISTANCE?
5 DETERMINE HOW MANY AMPERE TURNS ARE PRODUCED BY EACH SERIES FIELD COIL OF A COMPOUND GENERATOR, GIVEN THE FOLLOWING PARTICULARS:RATING = 100 KW; FULL LOAD VOLTS =600;SERIES FIELD TURNS PER COIL =8.5 ;RESISTANCE OF SERIES FIELD =0.025 OHM;DIVERTER RESISTANCE=0.068 OHM.
6 A 5KW 120 VOLT COMPOUND GENERATOR HAS AN ARMATURE RESISTANCE OF 0.25 OHM, A SERIES FIELD RESISTANCE OF 0.04 OHM, AND A SHUNT FIELD RESISTANCE OF 57.5 OHMS.ASSUMING A LONG SHUNT CONNECTION AND A VOLTAGE DROP AT THE BRUSHES OF 2VOLTS,CALCULATE THE GENERATED EMF AT FULL LOAD.
7 A SHORT SHUNT COMPOUND GENERATOR HAS A SHUNT FIELD RESISTANCE OF 77 OHMS.A SERIES FIELD RESISTANCE OF 0.08 OHM, A COMMUTATING POLE WINDING RESISTANCE OF 0.005 OHM, AND AN ARMATURE RESISTANCE INCLUDING BRUSHES OF 0.02 OHM , WHEN THE ARMATURE CURRENT IS 128 AMP THE GENERATED EMF IS 234.2 VOLTS CALCULATE THE POWER DELIVERED TO THE LOAD.
