Abstract

The capacitor measuring transformer has transistor, measuring capacitor, inductivity of oscillatory circuit and power source. To the transformer adjustment feedback capacity is included, dividing capacitor, the first, the second and third resistors of transistor shift. As transistor field channel transistor is used, between the drain and the gate of this one measuring capacitor is included. Between the source and the drain of the transistor adjustment feedback capacitor is included, inductivity of oscillatory circuit and first resistor of shift are included between the gate and the drain of the transistor connected to the common bus. The second and the third shift resistors are included between the power source and the source and the drain of the transistor, this is through dividing capacitor connected to the output.
