Claim:
1. A capacitor divider voltage sensor for a circuit with a line conductor, comprising: a continuous length of at least one flexible substrate with opposing first and second conductive surfaces separated by a dielectric film formed into a plurality of different layers, wherein the different layers provide; (a) a plurality of voltage sensor conductive layers associated with the first conductive surfaces and having sensor to ground interface surfaces, wherein respective voltage sensor conductive layers are electrically connected to each other and a sensor output voltage Vs; and (b) a plurality of conductive ground layers associated with the second conductive surfaces and connected to electrical ground, the conductive ground layers interleaved with the voltage sensor conductive layers so that a ground layer resides between adjacent voltage sensor conductive layers, wherein the plurality of voltage sensor conductive layers with the sensor to ground interface surfaces includes a first voltage sensor layer that is closest to the line conductor.
