An HV divider stepping down an input high voltage in HV systems includes a primary part with first and second assemblies within an insulator and a divider input terminal. The first assembly is a first capacitor stack having first high and middle voltage capacitors. The second assembly has a second capacitor stack and resistor stack in parallel. The second capacitor stack has second high and low voltage capacitors. The resistor stack has high and low voltage resistors. The secondary part has an electromagnetic unit and a secondary part output set has:
a first output terminal subset, deriving from a first intermediate terminal processed through electromagnetic unit, to provide a first output voltage subset for measuring amplitude of the input voltage at nominal frequency range;a second output terminal, deriving from a second intermediate terminal, to provide a second output voltage for measuring waveform of the input high voltage. |
