The Ability of Correct Evaluation of Selected Diagnostic Methods Used in the Diagnostics of Insulating System Generators
Original language description
The problem of diagnostics of insulating systems are often addressed only in terms of laboratory measurements and simulations of real conditions, but mostly is not linked with practice. This article is connecting practice with diagnostics of insulating systems. It will focus on two diagnostic methods that are used for diagnostics of insulating systems of large rotating machines by Diagnostic group CEZ. There are method of measuring dissipation factor and method of measuring charging currents. It is generally known, dissipation factor dependence on temperature, but usually is solved only at laboratory conditions and possibilities. This article approaches the effect of temperature machines (changes in conditions), when measured on real machines - large hydro-generator from power plants used in the Czech Republic. The dependence of method measuring charging currents on temperature is not discussed much, but it turns out, it cannot be completely ignored in practice.
