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.
