The Circuit Master is a power conditioning device that reduces the amperage requirement of a facility’s inductive equipment thereby reducing its’ electric bill. The Circuit Master reduces the inductive load kVAR (kilovolt Amps Reactive) requirement, provides Harmonic filtering, thus reducing resistance noise and line loss, and provides TVSS (Transient Voltage Surge Suppression) which shunts power surges and spikes that may occur from internal transformers or from the utility. These work together in a seamless fashion to provide the treated equipment with clean and stable power which allows the equipment to perform at its designed operating levels. Additionally, the Circuit Master, through patented circuitry, has the ability to capture back EMF (Electro-Magnetic Flux) that is normally wasted power, phase match it, and store it in its capacitance for use by the motor upon demand. The net affect of all these features working together reduce the Amp draw of the equipment subsequently reducing the kilowatts drawn through the meter while also lowering motor frame temperature thereby prolonging the lifespan of the equipment.
A facility’s Power Factor determines how efficient the equipment operating within the facility is using power. Power from an electric utility company is delivered in kVAs (kiloVoltAmps) and not kWs (KiloWatts) as most believe. The kVA distributed throughout a facility is drawn into inductive equipment (motors and ballasted lighting) and then divided into two components: kWs and kVARS. The kVAR component of the power is used by an inductive load to generate and maintain the magnetic field required to operate the inductive load. This power is non-working and, in theory, is returned to the power grid. However, due to line losses, heat generation, and inefficiencies of the power grid, this does not happen.
The kW component is the working power and provides the power for the inductive load to actually perform its task. A facility’s Power Factor is calculated by the following formula:
Real Power (kWs)
Apparent Power (kVA)
The result of this equation is expressed as a percentage (i.e. 70% or .7). This shows how efficiently the inductive load is using the power that it draws through the service meter. The higher the Power Factor, the more the load is efficiently using the power it is drawing from the grid. Raising a facility’s Power Factor will result in a reduction of the electricity consumed by the facility’s equipment, thereby reducing the power bill.
Power Factor Correction:
The Power Factor correction components of the Circuit Master reduce the amperage needed by the equipment to operate. The main component of the Power Factor correction ability is provided by capacitors that store the power generated by the equipment’s motors. Every alternating current (AC) motor is also a generator. The power that the motor generates is not “in phase” with the power that it needs to perform its function, meaning that it does not match the 60-hertz sine wave of the power drawn through the meter. This is necessary for the motor to use any power supplied to it. The Circuit Master stores this out-of-phase power in its capacitors and, through its circuitry, “phase matches” this power to the power provided through the meter. The motor can then use this power to provide its kVAR component and reduce the amount of power the motor pulls through the electric meter. This in turn causes the Power Factor of the equipment to increase and reduces the consumption of kWhs by the equipment.
The Circuit Master’s high and low band pass filters remove harmful odd harmonics resulting in a smoother sine wave of the power supplied to a facility’s equipment. Harmonics are generated by all manners of equipment (computers, printers, motors, VFDs, etc.) and the odd harmonics are disruptive to the sine wave of the power in the power grid. The even harmonics cancel themselves out, so their effect is negligible. The odd harmonics disruption of the power’s sine wave directly affects the operating ability of the inductive loads. With lighting they cause bulbs to burn out faster resulting in increased costs not only for bulb replacement but also the labor to do so. A motor’s operating speed is adversely affected by these harmonics, causing the motor to speed up and slow down unnecessarily. This causes the motor to pull more power from the grid. This is likened to a car’s gas mileage when using its cruise control function. If the driver sets the cruise control and then drives in the mountains of Pennsylvania, the car is constantly speeding up and slowing down. This uses more fuel and costs the driver more money. If the same car using its cruise control is driving the same distance in Kansas where it is virtually flat, the car uses less fuel and reduces the driver’s cost. The untreated motor is like the car in Pennsylvania and the motor treated with a Circuit Master operates like the car in Kansas. Filtering out the odd harmonics from an inductive load’s power results in reduced consumption and prolonged equipment life.
TVSS (Transient Voltage Surge Suppression):
The final element of the Circuit Master is its TVSS component. This removes the surges and spikes contained in the power supplied from the utility company. The minor surges and spikes can expose equipment to harmful voltages and heat generation. The Circuit Master provides the inductive load with a clean source of voltage and reduces the power consumption of the load. The Circuit Master also provides surge suppression from large surges, sacrificing itself and protecting the facility’s equipment. Through its TVSS component, the Circuit Master provides clean, safe voltage to a facility’s treated equipment.
