Electrical motors are the driving force behind most equipment used in the nuclear sector an their reliability plays a major role in terms of safety and availability of a nuclear power plant. Electrical motors and mechanical systems are subject to deterioration and damage that can suspend operations, leading to expensive repair and downtime.

 

 

The system permits data acquisition and analysis of not only AC induction motors but also DC motors, synchronous motors, generators and transformers. EMPATH 2000 can identify a multitude of mechanical and electrical problems of power supply and load events in the motor or the equipment. Unique algorithms can reliably detect the early stages of rotor bar failures in induction motors. It allows acquisition and analysis of data from a variety of other sources such as accelerometers, proximity probes, or process measurements. This information, properly analyzed, can greatly enhance a predictive maintenance program. All data acquired will be scrutinized by the best analyses and trending will be closely watched for deviations. EMPATH 2000 saves time and precludes plant walk downs by monitoring plant motors and driven machinery from a central motor control centre. Therefore no constructional measures for the performance of the measurements are necessary.
