Brake test on three phase induction motor lab manual

2. To conduct load test on single phase and three phase induction motor. 3. To conduct test on synchronous generator (alternator) to determine the performance characteristics. 4. To conduct test on synchronous motor to draw the performance curves. Course outcomes: At the end of the course the student will be able to: 1. Perform load test on. EXP-6 Sumpner's test on a pair of single phase transformers EXP-7 Parallel operation of single phase transformers EXP-8 Scott connection of transformers EXP-9 Brake test on three phase induction motor EXP Separation of no-load losses of three phase induction motor EXP No-load and blocked rotor tests on three. pairs of voltages are º out of phase. If the three phase switch is connected in this manner, there would be no problem with phase ‘A’, but huge current would flow in phase ‘B’ and ‘C’, damaging the machine. To correct the phase sequence problem, simply swap the connection on any two of the three phases.

To perform braking test on three phase wound rotor induction motor and use the from ELECTRICAL at Ghulam Ishaq Khan Institute of Engineering Sciences Technology, Topi. Fig. 2. Connection diagram of blocked rotor test PHASE SEQUENCE TEST It works on the principle of Induction Motor. The principle of rotating type phase sequence indicator is like that phase motor. Consider the working of a motor for a better understanding of these indicators. For this motors, we require three phase power supply. and DC tests of a 3-phase, wye connected 40 HP, 60 Hz, V, induction motor with a rated current of A. The locked -rotor test is made at 15 Hz to minimize the errors due to saturation and skin effects. Determine the motor parameters and the total core, friction and windage losses. Draw the approximate equivalent circuit for the motor.
