Alternator Test Rig

The Alternator Performance Test Rig is PC enabled where different parameters are selected by the click of the keyboard / mouse and the results are displayed on the screen.

Following tests are conducted :

• Rotor Energizaion


• WL ON test


• Cut in speed test


• Output @ speed 1 (1500Rpm)


• Output @ speed 2 ( 3000rpm)


• Output @ speed3 (6000 Rpm)


• Regulating Voltage (5000Rpm)


• ERPM & Blocking diode


• Zero output test


• WL End

Diode Test - The diode are tested inside the alternator by applying a constant current source across the terminals and measuring the drop across the diode.

Regulation test - The alternator is made to run at a speed of 6000 rpm using a motor, the output from the alternator is loaded for 30% of the rated capacity measuring output voltage which is compared to the set limits and accordingly the results are declared.

Load test- It is similar to the regulation test except the load of the alternator will be 80% of the rated load. The voltage, current and the speed of the alternator are measured and compared to the set limits and accordingly the results are declared.
