AIM
To conduct load test on three-phase Slip Ring induction motor.
APPARATUS REQUIRED
PRECAUTION
The motor should be started without any load.
PROCEDURE
1. Connections are given as per the circuit diagram.
2. The TPST’S is closed and the motor is started using online starter to run at rated speed.
3. At no load the speed, current, voltage and power are noted down.
4. By applying the load gradually with the help of spring balance and brake drum arrangements.
5. The speed, current, voltage, po ....etc

AIM :
To conduct a direct load test on a 3-phase slip ring induction motor and to draw the performance characteristics.
FUSE RATING-
FOR- STATOR- 125% 0f 7.5A = 10A
FOR ROTOR – 125% of 11A = 15A
THEORY:
Slip ring induction motor is also called as phase wound motor. The motor is wound for as many poles as the no. of stator poles and always wound 3-Ф even while the stator is wound two-phase. The other three windings are brought out and connected to three insulated slip-rings mounted on t ....etc

AIM
To conduct the slip test on three phase alternator and predetermination the regulation through vector diagrams
APPARATUS REQUIRED
PRECAUTION
1. The Motor field Rheostat should be kept in minimum resistance position.
2. The Alternator field should be kept open throughout the experiment.
3. The direction of rotation due to prime mover and due to the Alternator run as the motor should be same.
4. Initially all the switches are kept open
PROCEDURE
1. The name plate details of the motor an ....etc

FUSE RATING:
(a)For Motor- 125% of rated current
= 125% of 17A=21.25A=25A
(b)For Alternator- 125% of rated current
=125% of 4A= 5A
THEORY:
In a salient pole alternator, the reactance of magnetic circuit along is along its quad stator axis. The alternator is driven by auxiliary prime mover at a speed slightly less than the synchronous speed under these conditions. The armature current is when the armature current mmf is in line with the field poles. The reactance by the magnetic field current is minim ....etc
