Electrical signature analysis differs from many other portable reliability testing technologies because it evaluates the entire motor system, including incoming power, the motor electrically and mechanically, and the driven load.
This chart illustrates the capabilities of electrical signature analysis. Green indicates that a developing fault can is identifiable at an early stage and you can track it for predictive maintenance purposes. Yellow means a fault is there but may be difficult to trend or detect at its earlier stage.
The ATPOL II™ connects to the motor system using portable current and voltage probes or a permanently installed connection box. Portable probes are available in a wide selection of voltage and current ranges.
The ALL-SAFE PRO® installs between the starter motor drive and the motor. Current transformers are provided, and you can see them installed in this bucket. When the bucket is closed, the connection cable between the device and the ALL-SAFE PRO® is attached, allowing the technician to collect motor data without opening the electrical panel. This setup provides several advantages over portable connections. It promotes user safety, raises the number of motors that you can test each day and eliminates probe connection errors during data collection.
Once the test starts, the instrument takes 60 seconds to collect the required data. Using the ATPOL II™ Bluetooth interface, we can control the instrument up to 10 meters away. This image shows the software in virtual instrument mode, and all instrument functions are compatible with remote operation.
Because ESA evaluates incoming power, the motor and the driven load, it will improve the detection phase of your predictive maintenance program. The philosophy of the detection phase is to rapidly survey as many machines as possible. The detection phase identifies potential machine system failures. The faster you can do these surveys, the more machines you can analyze, resulting in a more effective program.
