Frequently Asked Questions About the BPU™ system


The BPU™ improves the poor power quality caused by poor harmonics, unbalanced phases, surges, and poor power factor and stores this wasted energy in the iterative transformer controller. The iterative transformer is able to capture and store and then recharge the capacitors that become the least resistive circuit. Thus, the loads will draw from the BPU™ first and then from the utility meter thereby reducing the kilowatts consumed. The patented electromagnetic theory practiced in the BPU™ iterative transformer provides for the storage and recharging of the capacitors.

No. The BPU™ provides both power factor correction and kWh/demand reduction. The design balance that Basic Power reached provides power factor correction but not to the detriment of demand reduction.

  • Phase Imbalance some impact
  • Harmonics filtering / Recycling first highest reduction comes from harmonic mitigation. Harmonics affect the voltage and current and the BPU™ will auto adjust keeping them in phase with a reaction time of 1 millisecond per cycle.
  • Voltage optimization some impact
  • Power Factor improvement second greatest impact
  • Surges & Transients close third depending on demand billing and the type of equipment being operated

The main point is that the BPU™ auto-senses what is occurring in the building and adjusts the magnetic reactor to respond in a millisecond per cycle to the facility conditions. All of the conditions noted above created inefficiency in delivering good power quality and the BPU™ is able to sense and adjust to varying power quality.

  1. Not at this time.
  2. Limited to 480 volt circuits at this point although research has been done at higher voltages up to 1,400V.
  3. See attached specification sheet. Basic Power is able to deliver 120V single phase; 208V 3-P; 380V 3-P; and 480 3-P. To handle the various kWh range of uses, multiple 2 units may need to be installed in parallel in the breaker panel if necessary. Also, a BPU™ could be installed on the main panel and other smaller units installed on sub- panels or specific equipment. In other words, multiple BPU™s can be installed and, through the auto-sensing feature, they will work in conjunction to improve power quality reducing kWh. Each unit must have a separate circuit breaker to hook into.

The BPU™ will clean up the noise from the rectifier/reactor creating the DC.

Cleans up power quality on the secondary side. Reducing the draw on the secondary side will reduce the draw on the primary side. Basic Power has never tested its impact on the primary side.

No and we have proven it in various ways. The BPU™s magnetic core acts more like a small generator.

Limited to 480 volt circuits at this point although research has been done higher voltage circuits up to 1,400V.

The specification sheet shows the design values. The high level analysis involves gathering the following data: (1) voltage, (2) estimated kWh per month, (3) range of running amps, and (4) power factor.

The first step in each case is to determine which BPU™ model(s) are needed for the application based on the parameters. A BPU™ must be installed on each transformer/panel. However, the total situation needs to be assessed so that the facility is not provided with more than is needed. This should not affect the overall cost of the installation.

  • Not having Bus coupler

The first step above is followed without consideration for the coupler being present.

In an unbalanced situation, Basic Power has seen the BPU™ balance up to 20 volts.

Voltage and current on the secondary side.

The BPU™ removes the odd and even harmonics around 300 and moves some harmonics up to 3,000. Mitigating the lower harmonics and maintaining higher harmonics is beneficial for the BPU™.

No. The BPU™ has built in protection due to the separate breaker in the panel and the breaker contained within the larger C models. Also, the BPU™ can be installed in parallel to a separate breaker in the panel without shutting down power to the facility.

The key parameters necessary to carry on the conversation are voltage, kWh/month, range of running/max amps, and power factor. We can assess fairly well with this limited data.

Of course this will occur and typically the BPU™ ranges provided will handle these situations. There are other ways to address fluctuations which involves installing multiple, smaller BPU™s to gain the most effective approach. That is why having access to an electrician or engineer who understands power is very important.

Yes, in some cases kWh reduction is not the customer’s problem. We installed two C-208 models in a garage door manufacturing company in August 2014 due to voltage sags knocking out sensitive control equipment causing production delays and repair costs. We are installing a I-480 model this month at a Medical Center on a problem boiler.

The BPU™ typically reduces voltages imbalances to within 1%.

Our units do represent an electrical load but as the BPU™s magnetic core acts like a generator that load is not registered at the utility meter or on a power quality analyzer. We love showing this surprising effect during our installation.
