Pa.tia. discha.ge dia.nosis is a. importa.t pa.t of monitoring a.d dia.nosing components of the power tra.smission system. Four different pa.ch a.tenna.structures for the detection of pa.tia. discha.ges a.e investiga.ed. These pa.ch a.tenna., which a.e rea.isa.le in a.va.iety of geometric structures, a.e a.rea.y the subject of resea.ch. They offer the a.va.ta.e of conta.tless detection without intervention in the test object or the mea.uring circuit, a.d a.so offer the possibility of a.ignment independent detection compa.ed to directiona. a.tenna.. However, it is importa.t a.d required to exa.ine different structures extensively a. the sa.e mea.urement setup a.d to compa.e their performa.ce.
