Technical diagnostics for power apparatus

This paper gives an overview of the possibilities and advantage of technical diagnostics. Maintenance diagnostics is an important step to prevent power equipment from failures or malfunctions. Therefore the task of diagnostics is the creation and selection of very effective test methods for specific arrangements. The aim of diagnostics can be defined in this way, that a maximum of information by a minimum of expenditure can be gathered from selected measuring and test methods by corresponding waveform acquisition and signal processing. The important aim of diagnostics and furthermore for maintenance is, in the deregulated and commercial electricity market, the increasing of the lifetime of power equipment and therefore delaying the obtaining of new apparatus by electric utilities
