MV Air Core Harmonic Filter Reactors

Power Factor Correction Systems

Power transmission and distribution systems are designed to operate with sinusoidal voltage and current waveforms within a specified frequency spectrum. Nonetheless, the integration of nonlinear loads, such as thyristor drivers, converters, and arc furnaces, into the system results in increased levels of harmonic currents, culminating in total current and voltage harmonic distortion. For these applications, power factor correction systems are commonly designed with Detuned Reactors. In medium voltage systems, Air Core Detuned Reactors and Dry-Type Detuned Reactors are preferred alternatives, as they dont have a magnetic core made of magnetic materials and do not reach magnetic saturation.

Air core detuned reactors are increasingly vital due to the proliferation of power electronics-based equipment and nonlinear loads. These reactors are designed to enhance power quality by mitigating harmonic distortions on the electrical grid. Harmonic distortions can lead to a variety of problems, such as device overheating, insulation failures, equipment malfunctions, communication system noise, increased noise in electrical machines, and improper operation of fuses or circuit breakers. Harmonic filter reactors can help prevent or alleviate these issues.

MV Air Core Detuned Reactor

Harmonic filters are typically constructed using passive RLC components and create a resonance path for harmonic frequencies. This helps to mitigate or reduce the spread of harmonic currents into the electrical grid. Reactors can be used in various configurations such as single-tuned, second-stage, and C-type filters, and can be connected in series with flexible AC transmission systems like static VAR compensation, static synchronous compensators, and high-voltage DC lines. Air Core Detuned Reactors are commonly used at medium voltage levels and do not have a magnetic core made of ferromagnetic materials, thus they do not experience magnetic saturation. These reactors can be installed without ferromagnetic components and can be deployed in both indoor and outdoor environments. In industrial applications, it is crucial to filter harmonics other than intermediate harmonics without amplification. Otherwise, the operational lifespan of devices may be reduced, and compliance with certain standards may not be achieved. Therefore, it is essential for reactors to possess a wide frequency range and to include harmonic components. The design of Air Core Detuned Reactors takes into account factors such as operating voltage and current, rated inductance , type of the application, dimensions, losses, and heat generation.

What is a Harmonic Filter Reactor?

After explaining Air Core Detuned Reactors, let’s answer the question “What is a Harmonic Filter Reactor?”. Harmonic filter reactors are components used to control and regulate harmonic currents in electrical systems. These filters are typically designed as parallel resonance circuits, filtering out unwanted frequency components by removing harmonic currents from the system.

This ensures that electrical systems operate more efficiently and safely. Harmonic filter reactors, particularly in industrial plants and power systems, improve system stability and extend the service life of devices.

What is a Detuned Reactor?

Detuned reactors are a type of electrical device utilized in power systems to manage harmonic currents and mitigate resonance . These reactors typically consist of a series tuning circuit with capacitors, which serves to regulate harmonic currents within the system and prevent resonance.

This, in turn, inhibits the escalation of total current and voltage harmonic distortion ratios, thereby promoting more stable system operation. as a result , detuned reactors are widely used in industrial facilities and power grids to solve harmonic related problems.

Benefits of MV Air Core Detuned Reactors

The primary benefits of MV Air Core Reactors are to improve power quality in electrical systems. These can be summarized as follows:

Elimination of Resonance Risk: In electrical systems, resonance arises when inductive and capacitive components interact at their inherent resonance frequency. MV Air Core Harmonic Filter Reactors mitigate this resonance risk, preventing undesirable fluctuations and voltage imbalances, thereby enhancing system stability.
