OPEN CIRCUIT AND LOAD CHARACTERISTICS OF SEPERATELY EXCITED D.C SHUNT GENERATOR

AIM:

To obtain open circuit and load characteristics of separately excited d.c shunt generator.

PRECAUTION

 All the switches are kept open initially.

 The motor field rheostat is kept at minimum resistance position.

 The generator field rheostat is kept at maximum resistance position.

PROCEDURE

OPEN CIRCUIT CHARACTERISTICS:-

 The connections are made as per the circuit diagram.

 After checking minimum position of motor field rheostat, maximum position of generator field rheostat, the supply side DPST switch is closed and starting resistance is gradually removed.

 The motor is started using three point starter.

 By varying the field rheostat of the motor, the speed of the motor is adjusted to the rated speed of the generator.

 By varying the generator field rheostat, voltmeter and ammeter readings are taken

MODEL CALCULATION:-

Armature current, Ia = IL = If

Generated EMF, Eg = (V + Ia Ra)

RESULT:

Thus the open circuit and load characteristics of separately excited D.C. shunt generator
