This paper presents the implementation of AT mega 32(L) processor to diagnosis the over-voltage, under voltage, over voltage, under current, over current faults. The Induction motors are most widely used motors in industrial, commercial and residential sectors because of enormous merits of these over the types of available electric motors, as the workhorse in industrial applications. However, induction motors are susceptible to many faults in industrial applications. The early detection of these deteriorating conditions in incipient phase and its removal is necessary for the prevention of external failure of the induction motors, reducing repairs costs and motor outage time. The various types of external faults in induction motor are single line-to-ground fault, double line-ground fault, line-line fault, single phasing fault, locked rotor, under voltage, overvoltage, phase sequence reversal of supply voltage and mechanical overload. This proposed method is applied to a 3.3KW three phase induction motor using A hardware implementation was carried out with the usage of ATmega-32(L) Microcontroller for the online-monitoring of faults. The effectiveness of the proposed system has been confirmed by experimental results. © EuroJournals Publishing, Inc. 2012.
