Abstract

Measurement of the capacitance and the dissipation factor of the high-voltage machines insulation systems is one of several method used in the technical diagnostics. This paper deal with the development of instrument designed for measuring capacitance and dissipation factor of such machines. There is described principle of ratio measurement method as well as developed hardware based on FPGA application. Finally the measurement error analysis is given and its correction is presented.

Keywords
