FAQ

Active Harmonic Filtration (AHF) improves energy efficiency by reducing losses associated with harmonics, such as heating in transformers and motors, and improving the overall performance of electrical equipment.

Yes, Active Harmonic Filters (AHF) can improve power factor as a secondary benefit by compensating for reactive power, in addition to filtering harmonics. Some active filters are specifically designed to provide both harmonic filtration and power factor correction.

Active Harmonic Filters (AHF) are commonly used in industrial facilities, commercial buildings, data centers, hospitals, and any other locations with significant non-linear loads and stringent power quality requirements.

The benefits of using Active Harmonic Filters (AHF) include improved power quality, reduced electrical losses, extended equipment lifespan, compliance with harmonic regulations, enhanced system reliability, and reduced risk of overheating and equipment failure.

An Active Harmonic Filter (AHF) works by continuously monitoring the power system and injecting compensating currents to cancel out the harmonics generated by non-linear loads. It uses power electronics to create these compensating currents in real-time.

Harmonics are typically caused by non-linear loads such as variable frequency drives (VFDs), uninterruptible power supplies (UPS), computers, fluorescent lighting, and other electronic devices that draw current in a non-linear fashion. (AHF)

Harmonics are problematic because they can cause overheating of equipment, increased losses, malfunctioning of sensitive devices, interference with communication lines, and reduced overall system efficiency. They can also lead to premature equipment failure. (AHF)

Active Harmonic Filtration (AHF) is the process of using active filters to reduce or eliminate harmonic distortions in electrical power systems. These filters dynamically adjust to cancel out unwanted harmonics, improving power quality and system performance.

Yes, by reducing the reactive power and improving voltage regulation, PFC can reduce the stress on electrical equipment, thereby potentially extending its lifespan.

Choosing the right PFC equipment involves assessing the type and size of your load, the variation in load, and the current power factor. Consulting with one of our PFC specialists can help in selecting the most appropriate solution.

Capacitors improve power factor by providing leading reactive power, which cancels out the lagging reactive power drawn by inductive loads, thus improving the overall power factor. (PFC)

Power Factor Correction (PFC) works by adding devices such as capacitors or synchronous condensers to the power system. These devices generate reactive power that offsets the inductive reactive power drawn by the load, thus improving the power factor.

Dash Control Systems offers full installation support, including initial assessments, system design, and integration. For maintenance, we provide regular check-ups and service to ensure that PFC devices are functioning optimally and delivering expected benefits.

Installing PFC devices from Dash Control Systems can lead to significant cost savings on energy bills, improved efficiency of power supply, reduced risk of equipment malfunction, and compliance with utility regulations on power factor. Additionally, our PFC devices are designed for reliability and easy integration with existing electrical systems.

If your facility has a power factor less than ideal (typically less than 0.95), it might benefit from PFC devices. Common signs include high electricity bills, overheated electrical components, and penalties from utility companies for low power factor. A detailed power quality analysis by our specialists can determine if your facility would benefit from PFC.

Power Factor Correction is important because it helps in reducing electricity costs, enhancing the capacity of the electrical system, and minimizing energy losses. It also reduces the load on the electricity supply grid and decreases the environmental impact by lowering greenhouse gas emissions from power plants.

Power Factor Correction (PFC) is a technology used to improve the power factor of electrical systems, making them more efficient by reducing the amount of reactive power produced. This results in improved energy efficiency and lower electricity costs, as well as reduced strain on electrical components.
