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

Based on closed form expressions for the power frequency voltages and currents in a typical distribution network, the voltage regulation VR at any time point during the day could be evaluated. It will depend primarily on the network configuration, the daily load curve, the load density and its power factor as well as level of the reactive power compensation.

The computed at a certain time?t? can give a useful indicator for the voltage constancy over the network at that time point. The concept of ?Global Voltage Regulation? is introduced. Th ....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
