FIELD: electrical measuring instrument.
SUBSTANCE: according to the method for analysing the state of the electrical working means, test voltage is applied to the measuring instrument. The measuring signal is then recorded at the connection point (AS) of the measuring instrument. Depending on this measuring signal, the transmission parameters are determined, which characterize the transmission of the signal from the partial discharge point in the measuring instrument to the connection point (AS). Depending on these transmission parameters, at least one partial discharge characteristic value is determined.
EFFECT: implementation of the claimed group of inventions will increase the accuracy of the partial discharge analysis due to the fact that an improved concept for measuring the partial discharge of an electrical measuring instrument is proposed.
