AVR stands for automatic voltage regulator. The main function of AVR is to maintain the established voltage to the MSB or to the consumer. IT maintain the terminal voltage (which is preset) of the alternator. It is done by taking the sample from two phase to the AVR(which contains OPAMPS and other summing ckts) where it is compare with the preset value. Any deviation from the set value give an output (error in either direction (+ or -). This error is processed and finally a dc voltage output comes out from AVR which is fed to the excitation system. The sign will decide that excitation to be reduce or increase to maintain the set output voltage. This process is a continuous measure so the terminal voltage is always as set at AVR as per requirement.

why do we measure VIBRATION in -24vdc and why we adjust gap voltage -9vdc to 10-vdc? i am trying to get this information since 5 years, yet i haven't get reliable answer, i hope i can get from you.
A 15 kw squirrel cage motor having a maximum efficiency of 90% on a continuous full load has temperature rise of 42 degrees celcius after 30 min and 52 degrees celcius after 1 hr under the above operation conditions. a) calculate its final steady state temperature rise on continuous load and the heating time constatnt. b) if the motor is operated on a short load for 9 min estimate its temperature rise. c) calculate the maximum overload that can be applied on a short, 9 min rating so that the temperature rise is the same as the final steady state temperature rise on continuous load.
