6 FAQs about [Energy storage due to stray capacitance to ground]

What is stray capacitance to ground?

The stray capacitance to ground is directly related to the distribution of the electric field around high-voltage electrodes [ 22 ]. It is a recognized fact that the effects of stray capacitance can be determined by means of FEM-based approaches [ 12, 23 ].

How does stray capacitance affect voltage distribution?

However, such electrode generates a capacitance to ground, which is often higher than the stray capacitance of the divider itself, thus affecting the voltage distribution along the resistors [ 26 ]. Stray capacitance appears between the divider and ground or between the divider and grounded objects.

How can stray capacitance effects be modeled?

Stray capacitance effects can be modeled by means of numerical simulations using finite element analysis (FEA) since it is a recognized and well-suited method to deal with complex geometries [ 16] and with high-voltage environments [ 17, 18 ].

Where does stray capacitance come from?

The stray capacitance originates from the electric field lines directed from the divider to ground. Such lines can be contoured by using a big toroidal or circular-shaped shielding electrode placed at the high-voltage terminal, with a diameter comparable to the length of the divider, so for large dividers, this solution is unpractical.

What causes a stray capacitance?

Nearby surfaces separated by an insulating medium such as air, subjected to different electric potentials, induce a stray or parasitic capacitance, and therefore this configuration acts as a capacitor. High voltages and high frequencies tend to amplify the effects of the unwanted stray capacitance.

How is stray capacitance determined?

It is a recognized fact that the effects of stray capacitance can be determined by means of FEM-based approaches [ 12, 23 ]. The capacitance can be calculated from the ratio C = Q/U, defined by the charge Q stored in the system and the electric potential U, supposing that the system under analysis is far from other charged bodies [ 3 ].
