A HV divider for stepping down an input high voltage (VIN) in HV systems, comprising a primary part (P1) with a first assembly (A1) and a second assembly (A2) included within insulating means (INS) and having for input the same input terminal which is the divider input terminal (&Tgr;IN); the first assembly (A1) being a first capacitor stack comprising a first high voltage capacitor (C1H) and a middle voltage capacitor (CM); the second assembly (A2) comprising a second capacitor stack and a resistor stack electrically connected in parallel to each other; the second capacitor stack comprising a second high voltage capacitor (C2H) and a low voltage capacitor (CL); the resistor stack comprising a high voltage resistor (RH) and a low voltage resistor (RL); wherein the secondary part (P2) comprises an electromagnetic unit (UEM) and wherein the secondary part output set ( TOUT1,TOUT2 ) comprises at least: - a first output terminal subset (&Tgr;OUT1) t deriving from a first intermediate terminal (&Tgr;I&Ngr;&Tgr;1) processed through electromagnetic unit (UEM), arranged to provide a first output voltage subset (VOUT1) to be used for measuring the amplitude of the input voltage (VIN) at the nominal frequency range; - a second output terminal (&Tgr;OUT2), deriving from a second intermediate terminal (TINT2) t arranged to provide a second output voltage (VINT2) to be used for measuring the waveform of the input high voltage (VIN). |
