ANALYSIS OF VOLTAGE AND CURRENT CONDITIONS AT HIGH VOLTAGE ELECTRIC NETWORK, MEASURING OF SURFACE VOLTAGE GRADIENT AND TOUCH VOLTAGE

Karel Sokanský, Stanislav Mišák

Abstract

A determination of voltage and current conditions were needful for increasing reliability and for reduction of a number of faults in the high voltage electric network. Increasing effectiveness and selectivity of readjusting relay protections evaluated faults, easier dimensioning of devices in the high voltage electric network and so on is possible by virtue of results from this analysis. The analysis of faults, including diagnostic of electric network devices, forms basis for reliability working of electric network and basis for design of protection systems.
