A capacitor assembly includes a primary capacitor and a secondary capacitor formed on a substrate. The primary capacitor and the secondary capacitor can be connected by a conduction line. The conduction line can be formed from a thin metal connection. The conduction line can be severed, i.e., trimmed, to finely tune a capacitance value of the capacitor assembly. The capacitor assembly can allow for tighter tolerance and wider variance of the capacitance value of the capacitor assembly. The capacitor assembly can be trimmed after installing the capacitor assembly in the circuit, thereby enabling fine tuning of the capacitance value of the capacitor assembly for applications requiring precision tunable capacitance.

Systems and methods for calibrating a low-power voltage transformer (LPVT). Systems include a capacitive voltage divider and a variable capacitance device connected to the capacitive voltage divider.
