A high voltage capacitor for a voltage divider is described that is configured to sense an elevated voltage for medium and high voltage electrical distribution networks. The high voltage capacitor comprises a high voltage electrode, a measurement electrode, and an dielectric material disposed between the high voltage and measurement electrodes, wherein the dielectric material consists essentially of lanthanum oxide-zirconium oxide-titanium oxide (LZT) glass filler disposed in an insulating polymer matrix such that the capacitance of the dielectric material does not vary by more than +/−0.5% in the temperature range of −20° C. to 60° C.
