High-voltage capacitors are power devices designed to store, stabilize, and compensate for electrical energy in high-voltage networks. They ensure the proper operation of substations, industrial facilities, reactive power compensation systems, and high-voltage converter stations.

These capacitors are used for:

reactive power compensation and improving the power factor;

voltage stabilization and reducing network fluctuations;

operation in harmonic filters and high-frequency circuits;

pulse generation in high-voltage circuits;

energy conservation and optimization of transformer loads.

Purpose of Capacitors

Improving the energy efficiency of the power grid.

Reducing electricity losses.

Protecting equipment from overloads.

Operation in compensation and filtering circuits.

Generating high-voltage pulses in industrial systems.
