Abstract

In this contribution a system for the detection and evaluation of electrical broadband measured partial discharges (PD) on power transformers is introduced and discussed. The theoretical background for some features of the system like the PD localisation based on the use of sectional winding transfer functions (SWTF), are explained exemplary, whereas the operation of the system is described for two different transformers. The performed measurements could be carried out on-line due to an enhanced sensor technology, superior signal transmission techniques and improved digital signal processing, which enables a significant reduction of disturbing noise.
