Abstract

Impedance assembly (120) for use in a voltage divider for sensing an AC elevated voltage of at least 1 kV of a power-carrying conductor (10) distributing electrical energy in a national grid. The impedance assembly comprisesa) a PCB (170);b) a high-voltage contact (80) for connection to the power-carrying conductor;c) a first plurality of impedance elements (70) on the PCB, connected to the high-voltage contact and in series with each other such as to be operable in a first voltage divider (20) for sensing the voltage of the power-carrying conductor; andd) a second plurality of impedance elements (71) on the PCB, connected to the high-voltage contact and in series with each other such as to be operable in a second voltage divider (21) for harvesting electrical energy from the power-carrying conductor.
