<p>In a process to detect a fault during operation of an electric motor-powered pump, a monitoring has two electric wires linking the electric motor to a power monitoring system, and a further sensor monitoring a hydraulic parameter in the pump. The electrical and hydraulic values are logged and processed in an algorithm by a data processing system, the results being compared with pre-stored values. Also claimed is a commensurate pump monitoring system.</p> |
