The Energy Conservation Circuit is a patented circuit that provides economic savings when applied to existing electrical circuitry supplied by alternating  current. The device allows the magnetic field to be altered in such a way which  significantly reduces the power consumption necessary to operate a given load, whereby the more the load the greater the savings.

Introduction

The Energy Conservation Circuit is a device which attaches between the electrical power meter and the power distribution panel. It is a circuit  designed for an alternating current power source for use with primary and  secondary loads comprising a load isolating transformer having a magnetically permeable core.

The present invention involves a means for reducing the power consumption  from commercial public utility power supply lines while maintaining a power output to operate the conventional loads in businesses and residences driven by  alternating current power sources. The device utilizes a new concept in  electrical theory which was previously thought to have been fully exploited. The Energy Circuit when installed will allow for 13% to 25% of energy savings. Units have been tested and placed in operation in industrial sites in Los Angeles from  1985-93.

Product Description

The Energy Conservation Circuit is designed to handle voltages from  120/208 -120/240-277/480 at 60 cycles per seconds using up to a maximum of 240 volts. Two systems have been designed to date: the ETSL-3 and the ETSL-5. The ETSL-3 (3 KVA) uses a primary and secondary load functioning for electrical circuit specifications of 20 amps. It is designed to handle three 1800 watt  resistive loads (i.e. , lights and heaters) and three 1800 watt inductive loads  (i.e., fluorescent lights and motors). The ETSL-5 (5 KVA) which functions with 50 amp circuit specifications can be used to power up to three, three horsepower motors or three 2000 watts resistive loads or inductive loads or a combination  of both inductive and resistive loads. Future designs are planned for ETSL-100 which is a 100 KVA unit that can be used for a load of 100-400 amps for use in  power generating plants.

The Energy Circuit employs a transformer having three windings (or coils). The primary and secondary windings are wound in the same direction upon a  magnetically permeable core. A third winding is connected to a load and produces  a magnetic flux in the core in the opposite direction to the magnetic flux produced by electrical currents in the primary and secondary windings. The  magnetic field produced by the third winding proportionally decreases the power input of the primary winding while maintaining the power output of the secondary  winding.

Figure 1.  Alternating Current Circuit

Figure l. illustrates an alternating current circuit which includes a typical  commercial public utility alternating current power source (1) and a first load (2) coupled to a transformer (4). The transformer is interposed between the alternating current power source and the loads. The primary winding (5) is wound upon a magnetically permeable soft iron core and connected to the power source.  Current flow through the primary winding produces a magnetic flux in the  direction indicated by the directional arrows for half the AC cycle. The  secondary winding (6) is connected to the first load (2) and is wound upon the same core in the same direction as the primary winding (5). The secondary winding (6) produces magnetic flux in the core in the same first direction at  the same moment in time indicated by the arrows. The third or return winding (7)  is wound on the core in the opposite direction from the primary and secondary  windings, as illustrated in Figure 1, and is connected to a secondary load (3).

The third winding is wound on the same core as the first two windings (5 and 6) to produce magnetic flux opposite to that of the primary and secondary  windings. Figure 2 illustrates alternative schemes for the windings on a  magnetically permeable soft iron core. The direction of magnetic flux produced  by the third winding (7) is indicated by the arrows.

Thus, an electric power conservation circuit has been constructed in which the magnetic fields of these windings are equal in absolute magnitude, i.e., the product of current times number of turns in each winding is equal in absolute magnitude. The sum of the magnetic fields of the primary and return windings is equal to the total magnetic field of the transformer.

The transformer is ideally located between the main circuit breaker and the power distribution panel of a building. The secondary winding is connected to  most of the secondary circuits terminating in the power distribution panel, but  the third or return winding is connected to at least one of the secondary circuits. Preferably, the third winding is connected in line with the main power feed to all circuits. The public utility power lines are connected to the primary winding of the transformer. The flow of the alternating electrical current in the primary winding induces electrical current flow in both the secondary and third windings of the transformer to power the loads. (See Figure  3.)

The Technology

As in the past, when certain scientific theories have been accepted as fact, it is difficult for many scientists to accept that they have been wrong. Logically, this device goes against the tenets of current scientific theory  since more power is generated from the device than was originally input from the  original power source, that being the line feed from the electric company.

The energy savings is accomplished by balancing the electrical fields thereby  reducing the resistance to the flow of electricity. Thus, the new product does  not really produce more electricity, but rather maximizes the efficiency of the electricity that is already present. It lowers resistance and maximizes other  efficiencies to get the maximum power output with a minimum of electrical input. An illustration of the concept would be to use an analogy of two automobiles  with identical engines and horsepower. If one has superior aerodynamic design, it will produce faster speeds. The end result is that the superior automobile gets more power output for the gasoline consumed or fuel input.

The presence of the opposing flux of the third winding acts to increase the  impedance of the primary winding. This increased impedance results in a reduced  current flow in the primary winding, thereby reducing the current drain from the public utility power supply lines. Since the current flow in the secondary  winding is induced by the current flow in the primary winding, the secondary winding acts as a load with respect to the primary winding. The flux produced by  the third winding reduces the impedance in the secondary winding, but does not  reduce its output. Thus, the presence of the third winding on the transformer produces a magnetic field which decreases the energy input to the primary winding, but keeps the energy output to the secondary winding constant.

To produce an energy conversation circuit of high efficiency, the primary and  secondary windings of a typical ETSL unit would consist of 120 turns of wire,  while the third winding would have 50 turns of wire when the transformer is used with conventional 60 cycle power. Depending upon the number of turns and the  load magnitudes the transformer unit can reduce the power consumption necessary to operate a given load producing savings from 13 to 25% as compared with conventional public utility power supply systems. The ideal conditions for maximum efficiency and minimum energy consumption are: (1) the magnetic fields of all three of the windings are to be equal in absolute magnitude; (2) for  current times the number of turns in each winding to be equal in absolute magnitude; and (3) for the sum of the magnetic fields of the primary and the return windings to be equal to the total magnetic field.

Test Procedures and Results

A test was performed using the Energy Trimmer (ETSL-3) sized for a 40-100W secondary (fixed) load and a 0-1000W primary load. The test was performed to measure voltage, current and power of input, and the output. In each case a  computation was made of the power factor and there was an examination of voltage and current waveforms of each. The environment required a fixed secondary load of 75 watts and a variable main load of 0, 300, 600, and 900 watts (rated). The Energy Trimmer was placed on 5 of the lighting circuits within an electrical  panel which contained a total of 11 circuits.

The Energy Trimmer was connected to electrical loads which consisted of  incandescent lamp banks connected to the main primary and secondary outputs. An  adapter was used to connect volt-amp-wattmeter and oscilloscope at each  location. The same wattmeter, was utilized for all measurements at each location to eliminate differences in metering affecting results. Waveforms at each location were examined to insure that harmonic content remained within the range  of measurement accuracy of the meter. All measurements were made at fully stable  conditions, with the unit fed from a regulated source of +/- 0.1% line voltage.

In one demonstration at the test site, two meters were used simultaneously to  monitor the watts and volts. One monitored the input power and the other the power being dissipated in the loads. The results showed that only 1,013 watts  and 494 volts were supplied from the main power source, while 1,343 watts and 292 volts were delivered to the loads. By deactivating only one of the return windings which would deactivate a part of the Energy Conservation Circuit,  instead of requiring only 1013 watts, the system required 1247 watts of input power. When all the return windings were deactivated the system required 1,343 watts of input power. Thus, a savings averaging 300 watts was recorded which is  approximately 19% savings in electricity costs in running the lights on the facility.

Savings up to 22% have been measured at peak operating times. (See Table 1  and Figure 4.) The variation of the main load from 0 to 1000 watts caused no  apparent change in the secondary load, either in magnitude or waveform. It was  noted that as the load increased, the harmonic content of the primary current  decreased as the waveform shifted closer in phase to the primary voltage waveform so that the power factor improved with increasing load.

Both secondary and main loads were shown to draw a unity-power-factor current  with loads that are resistive, whereby, the Energy Trimmer furnished a sine-wave  to both primary and secondary loads. The result is a sine-wave whose voltage and  current are in-phase under all loading conditions. The waveforms of the feedback  circuit also exhibited similar waveforms to the primary indicating that the  ratio of feedback to input power is essentially constant.

With any appreciable load on the main load output, the harmonic distortion in  the primary current is low, and consists mostly of the third harmonic. No EMI is visible in any of the waveforms, so the device should not cause any power system  interference.

Conclusions

In short, a new advanced circuity is available for energy savings applied to commercial, industrial and residential use. It is a electrical control device  which is attached behind the electrical meter but ahead of the electrical control panel. The basic concepts of the device will not be disclosed until more  units are available in the field.

When the ETSL unit is activated--it decreases the use of energy being used in  the home, factory or industrial site regardless of size of the installation or the power demands of the user. Undoubtedly, other variations and modifications will need to be made to accommodate the needs on the global level. There is, however, one important overriding consideration for all workstations and  factories. The ETSL conservation circuit works within the energy grid system of  the existing major power utilities and is not technology positioned against the utilities as some forms of alternate energy technology and cogeneration. It is  completely safe and complementary to all energy utilities. Thus it is a benefit to both heavy industry as well as small users and does not interfere with  environmental considerations already in place with major and minor energy users.

The result of 10 years of research and experimentation at several factory facilities in Los Angeles and throughout the state of California has shown engineering observers and company users that the more they use the system the more they save, and when more return windings are added to  their facility further savings are realized. Clearly, considering the growth of new industry, costs of expensive new designs in the  work place, and the need to reduce the heavy power consumption in growing population areas, the ETSL units comes as a welcome addition to 21st Century  technology.
