Abstract :
This paper contains summary information on diagnostic technology principles including proactive maintenance strategy which comprises the following sections: motors on-line testing and defects location procedure; on-line diagnostic technology and data analysis; examples of test results, sensor installation in detail, and example of technical report. The Benefits of on-line diagnostics are as follows: determine - non-destructively - the probable extent of deterioration in service-aged medium voltage motors, pinpoint the location of deterioration, determine which motors and cables are likely to experience failure in the foreseeable future, decide whether wholesale replacement of motor and cable is required, or just certain sections, postpone motor maintenance and postpone cost of replacement.
