  • How is the scientific study different to similar power quality audits?
    The detailed engineering study, also known as the scientific study, involves a thorough analysis of harmonics and other measurement factors within the facility. These factors include active power (P [kW]), apparent power (S [kVA]), reactive power (Q [kVAr]), voltage (V), current (A), power factor (DPF), frequency (Hz), and transients caused by switching large electrical loads. Using detailed on-site measurements, simulations are conducted to model the electrical system. This includes finite element method analysis and load flow analysis to precisely calculate thermal losses due to harmonics, possible interactions between electrical loads, and harmonic resonances within the facility's electrical grid. These AI computed simulations are the proprietary know-how of Senerqon and are not implemented in similar power quality audits.
  • Why do we have to do an entire section of the plant for the Proof of Concept project to work? Why can’t we just install one of the interventions on one load and see the impact on that load?
    Senerqon's project works through the elimination of the the harmful interactions which occur between electric loads, such as the harmonic resonances. Only by holistically improving the power quality of the facility can we achieve such high energy savings numbers and not by isolating specific loads.
  • Do we need to shutdown the facility during installation?
    No, installation can take place piecemeal and we only have to shutdown one load at a time.
  • What downtime is required for installation?
    The time required is 30 minutes per load.
  • Do we need to change the layout of our production line?
    No, connection of the interventions is in parallel, so we can move the panels further away from the loads, if space is restricted.
  • Is maintenance included on Senerqon's projects?
    Maintenance is free for the duration of the payback period, under warranty. After the payback period is concluded, we can sign a maintenance contract for a yearly period or more, for a fraction of the project cost.
  • How is the efficiency of the system monitored over time?
    We can either repeat measurements at set intervals, re-run the mathematical predictive models or install (at extra cost) a remote surveillance system to observed the savings live.
  • How much is a maintenance contract after the expiration date of warranty?
    It depends on the project, but it's certainly way less compared to the annual energy savings benefit.
  • What is the lifespan the equipment?
    More than 25 years, if basic maintenance is conducted.
  • What support is available from Senerqon following the warranty period and at what cost?
    Remote and onsite support are available either under a maintenance contract or on a per-case basis.
  • When upgrades/additions are made to our electrical system what is required to reconfigure in regards to extra systems?
    If the additions result in less than a 20% increase in the total installed apparent power, no additional systems are required; only reconfiguration of the settings in the existing system controllers is necessary. However, if the increase exceeds 20%, additional systems may be needed.
  • How does the Senerqon Group's project exactly reduce energy consumption?
    Energy savings are achieved by improving the efficiency of motors and power transformers and by reducing thermal losses in the electrical installation, from the electric loads all the way up to the provider’s energy meter. A. Motor Efficiency Improvements: Drastically reducing interactions between the motor and other electrical loads, particularly addressing 5th order harmonic resonances that cause braking. Eliminating voltage drops and stabilizing voltage at nominal levels. Efficiency decreases when voltage falls below the nominal levels (e.g., from 400 to 395V). These improvements result in a 5% to 7% energy saving. B. Power Transformer Efficiency Improvements: Reducing scattering losses in the magnetic field, thereby decreasing iron (Fe) losses. Reducing copper (Cu) losses in the transformer’s windings. The Senerqon Group project minimizes interactions between power transformers and electric loads, reducing resonance phenomena of 3rd, 5th, 7th, and other order harmonics. This leads to a 1% to 2% energy saving. C. Reduction of Thermal Losses: Significant decrease in skin effect losses in the cables. Reduction of proximity effect losses in the cables. Reduction of eddy current losses. Thermal losses are drastically reduced by eliminating interactions between electric loads under all harmonic resonance scenarios due to the Senerqon Group project, resulting in a 1% to 2% energy saving.
  • Where do the Senerqon Group interventions connect into the electrical installation? Is it at the motor junction box? Is it at the MCC? What does the connection point look like?
    Our general aim and practice is to install project interventions as close as possible to the electrical loads. However, from a technical and financial perspective, this isn't always advisable. Therefore, we may sometimes place the interventions at the Motor Control Center (MCC). For example, if there is a large electrical load located far from its MCC, it is beneficial to install the intervention directly at the load for optimal results. Conversely, if the electrical load is small and has minimal impact on the overall system, the intervention will be placed at the MCC. It's important to remember that each electrical installation is customized. The scientific study conducted for each project addresses these and other issues. This study evaluates all relevant data, identifies crucial points, and, based on technical and financial criteria, provides optimal solutions for energy saving and power quality improvement.
