Laboratory high voltage capacitor with low PD level and low dissipation factor

High voltage capacitors are widely used in middle and high voltage laboratories and testing rooms. Capacitors are used for measurement of voltage in the form of voltage dividers. Injection and blocking capacitors are placed in the galvanic systems of partial discharges. And high voltage capacitors are also used in the high voltage as the part of laboratory bridge circuits. Common characteristics of these capacitors are the stability of parameters in time and voltage, low value of PD level. And usage as the capacitor with low value of dissipation factor (tan delta) for bridges. This paper is focused on the description of the parameters of these capacitors, their implementation and the function verification.
