Micro Controller Based Earth Fault Relay

Authors(2) :-S. Vasudevan, A. S. Viswanathan

One of the most common electrical motor used in most applications is inductor motor. This paper presents microcontroller based control system for protector of a Induction motor from earth fault. Due to electrical fault the windings of motor get heated which leads to insulation failure and thus reduce the life time of motor. This protection scheme protects the induction motor from earth fault from initial stage of insulation failure. It also measures the leakage current. Three phase induction motors are industry’s workhorses and widely used as electromechanical energy conversion devices. Although induction machines are considered relatively reliable and robust due to their simple design and well-developed manufactures technologies, failure do occur and may severely disrupt industrial process and even lead to disastrous accidents. To prevent these failure happen, many techniques have been developed for early condition monitoring. The computer based protection methods are costlier then old classical methods and complex. Hence to protect an Induction, motor easily a microcontroller based fault detection and protection is proposed. The proposed system is tested with setting of values presetted values, from the results, it is observed that the results are satisfactory, reliable gives quick response, cost effective and highly resatile.
