PQFLOW Methodology

The PQFLOW Methodology

Removing electronic anomalies to mitigate wasted electricity use and minimize maintenance costs.

Power quality has become a major issue for facilities managers. Electrical distribution equipment has not changed much in the past 30 years, however the types of electrical equipment using electricity has changed considerably.

Even as our electronic motor equipment has gotten more efficient, we have seen an exponential growth in electronic load types that are consuming more and more electricity. The explosion in electronic loads has created problems for the distribution system in buildings that were never designed specifically for such large increases in these types of loads. Some very complex power quality issues, such as high harmonic current draw, are wreaking havoc on building power systems. Maintenance costs, including the repeated replacement of motors, has become the norm.

PQFLOW offers a solution to these power distribution headaches. Not only can we reduce wasted electricity, but more importantly, we can reduce these costly maintenance issues and improve the general power quality of the building’s electrical distribution system. PQFLOW is not a one-size fits all magic box, but rather a total engineering solution based on customized measurement and design for a particular building and electric load. We manufacture our power conditioning equipment based on documented electromechanical theory and the most current electronic technology.

PQFLOW is a four-step process to savings:

Identify: The PQFLOW system begins with a customized site audit and analysis of your facility. The power usage profile is derived from several perspectives. One is from current load and harmonic levels present during maximum operation. Another is from the previous year’s power bills. By extrapolating the demand data, and kilowatt hour usage, we can plot the overall power usage profile, and then compare that against the audit data we collect to calculate the percent of operation, and the hours of operation of the actual data we have collected. We then calculate the changes we can make to the electrical system with our equipment. This calculation includes the outcome of the resultant changes to the electrical supply voltage, harmonic levels, and line losses and is applied to the previous power billing history. This produces a linear regression to estimate the changes to the energy consumption and thus the increase or reduction in projected expenditures.

Build: Once savings is guaranteed and energy loopholes are identified, we engineer a total Power Quality (PQ) solution, including custom equipment, planning and development.

Install: Your custom-made solution is installed at your location, protecting your equipment from electrical anomalies except complete power interruption.

Save: Copper loss (also known as I squared R losses) on facility feeders are minimized by keeping harmonics close to the non-linear source and stopping movement of other magnetizing currents.

Our goal is to ensure that our services will provide a quick return on investment. We typically see an ROI of 24-36 months, based only on electricity savings, while this ROI is reduced to 12 months, if we also include the savings from reduced maintenance and replacement of failed motors.
