Components for Power Factor Compensation - Hmotnost v [g] - 8800

Reactive Power Compensation

To operate certain electrical equipment, whether on the side of electrical networks or energy-consuming devices, it is necessary to create an electromagnetic or electric field. This is achieved either by inductance (in motors, transformers, etc.) or capacitance (capacitors, electrodes). In inductive components, current lags behind voltage due to phase shift, while in capacitive components, voltage lags behind current. The behavior of individual elements can be described by their impedance, which includes both the active and reactive components. It is termed “reactive” because the energy supplied to this impedance cannot be utilized, yet it is still transferred between the source and the load. This energy transfer causes losses within transmission and distribution network components, which are dissipated as heat. Therefore, it is highly effective to install additional equipment into electrical networks to modify their characteristics (impedance), thus eliminating or compensating for these losses.

What is Reactive Power

Reactive power can be thought of as energy generated due to phase shifts in windings or capacitors. It is termed "reactive" because it cannot be utilized, yet it is still transferred between the source and load, burdening all elements within the transmission system.

Appropriate Compensation

• Individual Compensation - Each inductive load is paired with a corresponding capacitor.
• Group and Central Compensation - A suitable compensation panel automatically connects capacitors in steps as needed.
• Decompensation - Using decompensation chokes eliminates network capacitance.
• Protected Compensation - Filter-compensation equipment (for harmonic distortion correction).
