ATTACHED PAPER SHOULD BE DEVELOPED AS IT IS This paper presents a novel simplified cost effective

binary based mechanism for eliminating problems in existing

condition monitoring and diagnostic techniques. The existing

techniques are engraved with problems like high cost of their

implementation, failure to detect multiplicity of faults, complicated

diagnosis system, expert knowledge, inherent ambiguities etc. The

mechanism developed in this work gives flexibility to monitor faults

at incipient stage and avoid catastrophic cascading of faults that leads

to plant shutdown and consequent long repair/maintenance periods.

The developed system detects working status of sensors, location of

faults, no. of faults at that particular instant, acknowledgement of

faults, and health status of electrical machines connected to the

system. These diagnostic parameters have been extracted by

implementing a simple logic circuitry. The main advantage of this

system is that it can be applied to any rating of electrical machines.

The input parameters for the system are the outputs of the sensors

which are capable to measure variation in parameters like current,

voltage, flux, torque, speed, temperature, and vibration etc. due to

occurrence of faults. The test results of the proposed mechanism have

been found to be highly encouraging, accurate and extremely fast

providing the much needed protection of machines.
