XL TECHNOLOGY & POWER QUALITY BENEFITS
1. XL Systems Reduce Real Power KW Demand and KWH Consumption
- XL modules generate or induce up to 7,000 Watts per hour per module through electro-magnetic induction (EMI) to be consumed by downstream facility loads which displace and therefore reduce billed kW demand and kWh consumption upstream at the utility billing meter; this ultimately reduces monthly electric cost.
- Real Power Demand (KW) and Consumption (KWH) are reduced through amperage reductions on the circuit, which reduce “Copper Losses”, and through the reduction of Total Harmonic Distortion (THD) in amperage and voltage supplied to operating loads, which improves efficiency in motors and other equipment loads.
- The amount of KW and KWH reduction provided by XL Systems far exceeds that of any other energy conservation measure (ECM) including power factor correction capacitor (PFCC) equipment because XL Systems reduce THD in addition to improving power factor.
- Additionally, magnetic multi-coiled chokes in XL modules interlink the electrical phases and convert or reconstitute “Wasted Electrical Energy” like harmonics, transients, spikes and noise into “Usable Electrical Energy” which is injected back into to the electrical system to be used by downstream equipment loads.

2. XL Systems Convert Wasted Power to Usable Power
- XL modules filter and absorb wasted power inherent in electrical systems like transient voltage and current surges, voltage and current harmonics, line noise, etc. and convert or reconstitute them into safe "Usable Power" which is injected back into the electrical system to be consumed by downstream loads.
- The conversion or reconstitution of wasted power is a form of power conditioning that displaces and therefore reduces billed kW demand and kWh consumption upstream at the utility billing meter which in turn reduces monthly electric cost.
3. XL Systems Reduce Reactive Power, Apparent Power & Amperage
- XL modules reduce the reactive power on the circuit in a manner which does not create RLC resonance which makes XL modules compatible with Variable Frequency Drives (VFDs) when installed on their line side.
- A single XL power conditioning module will conservatively reduce reactive power from 5,000 VAR to 44,000 VAR.
- The reduction in reactive power (KVAR) results in a corresponding decrease in the apparent power (KVA) on the circuit. This, in turn, results in a decrease in the amount of amperage (AMPS) on the circuit, which results in a decrease in real power KW demand and KWH consumption as a result of reduced “Copper Losses” on the circuit. Copper losses manifest themselves as heat in motors and conductors and can reduce the useful life of motors, transformers and sensitive electronic equipment.
- The reduction in reactive power (KVAR) on the circuit also acts to “stiffen” the circuit by reducing overall circuit impedance. A “stiff” circuit will reduce the creation of voltage total harmonic distortion as a result of current harmonics.

4. XL Systems Improve Power Factor
- Power Factor is the ratio of Real Power (Watts) to Apparent Power (Volt Ampers – VA or KVA).
- Because XL modules reduce both Real Power Demand KW and Apparent Power Demand (KVA) at the utility billing meter, power factor is improved as it approaches unity or 100% which help equipment loads run more efficiently, cooler and last longer.
- Since XL modules do not create RLC resonance, any leading Power Factor will have no effect on the performance or reliability of connected equipment loads.
5. XL Systems Reduce Amperage (Amps)
- XL modules reduce facility load amperage (AMPS) by 10% to 20% which increases the operating capacity of utility transformers and customer electrical gear.
- Reducing facility load amperage (AMPS) also helps to reduce facility maintenance cost because equipment loads run more efficiently, cooler and last longer.
- A single XL module will conservatively reduce amperage in existing electrical systems by approximately 14 Amps to 39 Amps per phase.

6. XL Systems Balance Phase Voltages & Amperages
- XL modules balance phase voltages and amperages within and across 3 phase conductors which reduces waste and kW demand and protects inductive loads from electrical stresses such as internal imbalance, vibration, friction and excessive heat buildup and reducing the harmonics of 3-phase motors, machinery and transformers.
- Phase Balancing also helps to reduce facility maintenance cost because equipment loads run more efficiently, cooler and last longer.
7. XL Systems Improve & Regulate Voltage
- By improving voltage across each of the three phases (VAB, VBC, and VCA), circuit amperage (AMPS) is further reduced and motors will run cooler and last longer.
- Increased voltage will also lessen the likelihood of equipment tripping off due to utility voltage sags.
- Fluctuations in voltage are dampened by the coupling of the three phases of power supplied, which will lessen any likelihood of equipment tripping problems associated with voltage fluctuations.
8. XL Systems Reduce Harmonics
- XL Systems reduce Total Harmonic Distortion (THD) of the amperage and voltage on the circuit by passing all power generated within XL System through 60 Hz band-pass Filters.
- Because XL Systems are connected to existing electrical system circuits in parallel, some THD will continue to pass on to the operational loads. However, because a significant portion of the power supplied to the load is “choked” to 60 Hz, total THD supplied to the load is reduced. This action significantly reduces the THD in the voltage and current provided to the operating motors, thus increasing motor efficiency.
- Problems associated with circuit harmonics that XL Systems attenuate include:
- Excessive Neutral Currents, where voltage harmonics result in additional current on the circuit neutral conductor, resulting in additional heat, possible overloading and the need to install additional neutral conductors.
- Overheated transformers, where harmonics generated on the secondary side of a delta-wye transformer will circulate on the primary side of the transformer. Some types of transformer losses, such as skin losses and eddy currents will increase by the square of the harmonic order.
- Overheated solenoid coils and lighting ballasts.
- Positive, negative and zero sequence voltages on motors and generators, where certain harmonic frequencies will try to rotate the motor forward or backward, or simply heat up the motor.
- Incorrect reading power meters, especially disc type watt-hour meters and averaging type current meters.
- Failure of electronic equipment, including nuisance tripping and overload.
- Nuisance tripping of circuit protection devices including false tripping of relays and failure of UPS devices to properly transfer.
- Blown fuses and overheated power factor correction capacitors due to the cumulative effects of harmonic THD and RLC resonance.
9. XL Systems Provide Superior Spike & Surge Protection
- Inherent in XL Systems, but not measured, is the ability to provide superior spike and surge suppression to existing electrical systems and connected loads, as well as sensitive machines such as computers and NC equipment.
- A surge is any voltage increase lasting 3 or more nanoseconds.
- A spike is any voltage increase lasting less than 3 nanoseconds.
- XL Systems detect any surges or spikes traveling along one of the active phases and shunts it to the other two phases. From there, the transformer/choke sets within each XL module attenuate the surge/spike through the action of the “chokes”, which use capacitors and inductors to resist the change in voltage and associated change in current, and flatten out the waveform.
- The surge/spike is recycled as usable power for the circuit.
- If an XL “Wye” technology is specified for an application, the XL System will protect the circuit against ground fault transients or secondary lightning strike effects which can enter the circuit through the neutral conductor.
