👀 Did you know that mechanical air filters have a weak spot? The phenomenon known as the MERV curve, is where filter efficiency counterintuitively drops before gradually recovering and it most commonly affects fine & ultra-fine particles that are less than 1.0 microns (µm) in diameter. This bin size of particles includes many viruses 🦠, bacteria 🧫 and contaminants 🤢 found in wildfire smoke 🔥 . This article provides a brief overview of how GPS needlepoint bipolar ionization (NPBI™) technology works to help reduce PM and improve IAQ, effectively flattening the curve. ✔ ✔

Identifying harmonic problems in an electrical system. #Eaton Harmonics in an electric system can cause various problems that manifest through specific symptoms. The most common signs of harmonics include: 1. Overheating of Equipment: Transformers, motors, capacitors, and wiring can overheat due to excessive harmonic currents, which increase the load on these components. 2. Increased Neutral Currents: In three-phase systems, harmonics (especially third-order harmonics) can lead to elevated current levels in the neutral conductor, which can cause overheating and potential safety hazards. 3. Voltage Distortion: Harmonics can cause the AC waveform to distort from a pure sine wave, leading to voltage fluctuations that can affect sensitive electronics and equipment. 4. Unstable Operation of Electronic Devices: Sensitive devices, like computers and communication equipment, may experience frequent resets, errors, or erratic behavior because of harmonic distortion. 5. Tripping of Circuit Breakers and Fuses: Harmonic currents can cause protective devices to trip frequently, even at lower loads, due to the higher RMS current caused by harmonics. 6. Audible Noise: Harmonic frequencies, especially higher-order ones, can produce audible buzzing or humming sounds in transformers, motors, and other equipment. 7. Reduced Efficiency and Increased Power Loss: Harmonics increase losses in the system, reducing overall efficiency and increasing energy costs. 8. Failure of Capacitors and Power Factor Correction Equipment: Capacitors, often used for power factor correction, are highly susceptible to damage from harmonics, which can lead to their premature failure.

Traditionally, harmonics problems are addressed with filters and other mitigation devices—a band-aid approach that doesn't fix the root cause. But what if we could eliminate harmonics at the source? The SmartD Technologies Clean Power VFDs offer a solution by not generating harmonics in the first place. By integrating advanced power electronics, they deliver a pure sine wave output, maintaining system integrity without the need for additional corrective equipment. For engineers deeply versed in VFDs and their applications, it's time to rethink our approach. Instead of applying temporary fixes, let's adopt technologies that prevent harmonic issues entirely. Consider the long-term benefits of using devices designed for clean power. It's not just about solving problems—it's about enhancing performance and reliability from the ground up. #smartD #CleanPowerVFD #HarmonicElimination
