Bently Nevada has developed a diagnostic tool to enable a detailed diagnosis of electric generators or motor drives for compressors and better use of dynamic power information. The dynamic power transducer (DPT) measures the instantaneous power produced by a generator. Along with the instantaneous power output, it also measures instantaneous current and voltage outputs, which can help the user separate line problems from load problems. Instantaneous power, which includes static (average) and dynamic power components, can be used to detect short power spikes that could indicate an impending machine failure.
The static (d.c.) component of the instantaneous single- or ...
