Abstract

Et testapparat til visning av forekomsten av en elektrisk spenning i høy- eller mellomspenningsanlegg eller lignen- de har en koblingsdel (11) som over en koblingselektrode (2) er kapasitivt koblet til en høyspenningsførende kom- ponent (1) og utført for mating av en visningsinnretning (7). For å kunne foreta en test av funksjonsdyktigheten til koblingsdelen, har visningsinnretningen (7) en ekstra målegren som ved en minstetestverdi som overskrider en forhåndsbestemt driftstrømverdi med en forhåndsbestemt differanseverdi, genererer et ekstra kontrollsignal som genererer et eget teststrømvisningssignal.A test apparatus for showing the presence of an electrical voltage in high or medium voltage systems or the like has a coupling member (11) which is capacitively coupled to a high voltage conducting component (1) over a coupling electrode (1) and designed for supplying a display device (7). In order to be able to test the functionality of the coupling part, the display device (7) has an additional measuring branch which, at a minimum test value exceeding a predetermined operating current value with a predetermined difference value, generates an additional control signal which generates a separate test current display signal.
