Abstract
Multi-layer capacitor divider voltage sensors include a plurality of voltage sensor conductive layers having sensor to ground interface surfaces. Respective voltage sensor conductive layers are connected to each other and sensor output voltage Vs by continuations of material forming the interface surfaces extending therebetween. The voltage sensors also include a plurality of conductive ground layers connected to electrical ground, the ground layers interleaved with the voltage sensor conductive layers so that a conductive ground layer resides between adjacent conductive voltage sensor layers. A first voltage sensor conductive layer (closest to a line conductor) is electrically connected to the other conductive voltage sensor layers and output voltage Vs and has a sensor to conductor interface surface with a corresponding interface area. The interface areas and the gap distances are configured to provide desired capacitance for attenuation of conductor voltage Vc for a suitably sized Vs in a compact sensor package.
