Capability Analysis for Reliable and reProduciblE DIagnosis on Electrical Machines
Rotating machines are important operating equipment in the energy supply or in industrial processes. In the case of a fault, operating failures with high consequential costs can occur, so that operators have a high interest in a reliable and sensitive non-destructive diagnostic measurement method for the early detection of faults.
The project CarpeDiem is therefore investigating the suitability of Frequency-Response-Analysis (FRA) as a reproducible method for fault diagnosis on rotating machines. FRA is a commonly used, non-invasive method for detecting mechanical and electrical faults in transformers. It involves applying a peak-to-peak voltage of e.g. 10V over a frequency range of 2Hz ... 20MHz to an input terminal and measuring the damping and phase shift the voltage experiences as it passes through the equipment to the output terminal of the measurement. This individual fingerprint would be influenced by a mechanical or electrical change (such as a mechanical deformation or a winding short circuit) and is thus measurable. In the project, the accuracy of detecting different faults in different machines (synchronous/asynchronous, motors/generators) is to be investigated. Essential influencing factors are to be determined and evaluated. Suitable modeling and validation of measurements should enable statements on general validity and transferability.
