Evaluation of the Touch Voltage Recorded in the Compensated Network 22 kV During Earth Fault

Popis výsledku v původním jazyce

The paper focuses on the evaluation of the touch voltage measured during a series of experimental measurements performed in a compensated 22 kV distribution network equipped with an automatic system for the additional earthing of the affected phase. During the experiment, a metallic earth fault was artificially created in selected dis-tribution transforming substations. Two different network extents were tested, a basic one ? 300 A ? considered by Czech technical standards as a limit value for operatinga mixed distribution network and an extent of 800 A repre-senting a maximum value of the tested network. The paper analyses the level of touch voltage with respect to the tech-nical standards in force as well as with respect to the volt-age of the increase of the substation potential during the fault for 300 A and 800 A and assesses the influence of the additional earthing of the affected phase on the level of touch voltage.
