By synchronizing proprietary technologies across the electrical system, we create a fully balanced and optimized power network from source to load.
Continuously monitors load currents using high-speed DSP, detecting and cancelling harmonic distortion within microseconds — no manual tuning required.
The XPF generates equal-magnitude, opposite-phase compensating currents and injects them back through a voltage-source inverter (VSI), restoring the supply waveform to near-sinusoidal shape. Because the detection–compensation cycle occurs within microseconds, harmonics are mitigated instantly rather than waiting for steady-state conditions.
Closed-loop control continuously tracks changes in load current and harmonic spectrum. When load conditions fluctuate, the XPF automatically recalculates the required compensating current and adjusts inverter output in real time.
Triplen harmonics accumulate additively in the neutral conductor, causing neutral currents to exceed phase levels. The XPF detects and eliminates these zero-sequence components at the source.
By targeting dominant harmonic orders and injecting counter-harmonic currents, the XPF reshapes the current waveform to closely match an ideal sinusoid — reducing THD from 20–30% down to below 5%.

Continuously monitors phase voltages, corrects imbalances in real time, and actively compensates reactive current — freeing infrastructure capacity without physical upgrades.
Balanced voltage reduces negative sequence currents in motors, stabilizes sensitive electronics, minimizes nuisance tripping, and lowers localized overheating. Distributed voltage correction creates phase symmetry throughout the facility — from main switchgear to every end-use load.
When voltage is unstable, equipment draws excess current to maintain output, widening the gap between average and peak demand. Consistent voltage keeps motors at rated efficiency and demand spikes reduced.
Inductive loads draw reactive current that increases total flow without performing useful work. The LC Series dynamically adjusts phase relationships to compensate — without fixed capacitor banks that overcompensate at low loads.
Infrastructure is rated in kVA. When reactive current and voltage imbalance are present, that capacity is partially consumed by non-productive components. Stabilizing voltage and reducing reactive current frees capacity within existing infrastructure — no transformer replacement needed.

Xeco's Active Power Filters continuously monitor load currents using high-speed current sensors and digital signal processing (DSP). The controller analyzes the waveform in real time and extracts harmonic components using advanced algorithms.
Once harmonic distortion is identified, the APF generates equal-magnitude, opposite-phase compensating currents and injects them back into the system through a voltage-source inverter (VSI). This effectively cancels harmonic components at the point of common coupling (PCC), restoring the supply current waveform to near-sinusoidal shape.
Because this detection–compensation cycle occurs within microseconds, the system mitigates harmonics instantly rather than waiting for steady-state conditions.
Industrial environments often include nonlinear loads such as VFDs, rectifiers, UPS systems, and arc furnaces, which generate harmonics that vary with load conditions. Active Power Filters are designed with closed-loop control systems that continuously track changes in load current magnitude and harmonic spectrum.
When load conditions fluctuate, such as motor speed changes or sudden switching events, the APF automatically recalculates the required compensating current and adjusts inverter output in real time. There is no need for manual tuning or capacitor bank switching.
This dynamic adaptability ensures stable harmonic suppression even during rapid load transients, preventing voltage distortion and maintaining system reliability.
In three-phase four-wire systems, triplen harmonics (3rd, 9th, 15th, etc.) generated by single-phase nonlinear loads accumulate in the neutral conductor. These harmonics are additive rather than canceling, often causing neutral currents to exceed phase current levels, leading to overheating and insulation stress.
Active Power Filters detect zero-sequence harmonic currents and inject compensating currents that eliminate these triplen components before they accumulate in the neutral line. By suppressing harmonic distortion at its source, the APF significantly reduces neutral current magnitude.
This results in:
- Lower thermal stress on cables
- Reduced risk of transformer overheating
- Extended lifespan of distribution equipment
Total Harmonic Distortion (THD) is a key indicator of power quality, representing the percentage of harmonic content relative to the fundamental frequency.
Active Power Filters reduce current THD by precisely targeting dominant harmonic orders (e.g., 5th, 7th, 11th, 13th). By injecting counter-harmonic currents, the APF reshapes the overall current waveform to closely match an ideal sinusoidal waveform.
Lower THD levels provide several measurable benefits:
- Compliance with IEEE 519 or IEC harmonic standards
- Reduced overheating of transformers and motors
- Improved efficiency and reduced losses
- Stable voltage levels across the network
In many applications, Xeco's Active Power Filters can reduce current THD from levels above 20–30% down to below 5%, significantly improving overall power quality and system performance.

Xeco's Line Conditioners continuously monitor phase voltages and correct imbalances and fluctuations in real time.
At the circuit level, balanced voltage reduces negative sequence currents in motors, stabilizes sensitive electronics, minimizes nuisance tripping, and lowers localized overheating caused by uneven phase loading.
Across the entire network, distributed voltage correction creates phase symmetry throughout the facility. This reduces neutral currents, lowers transformer stress, minimizes feeder losses, and stabilizes bus voltage from main switchgear to end-use loads.
The result is improved equipment performance at the point of use and enhanced reliability across the full electrical distribution system.
Load factor is the ratio of average demand to peak demand over a billing period. Xeco's Line Conditioners improve load factor by stabilizing voltage and reducing inefficiencies that contribute to demand spikes.
When voltage is unstable or imbalanced, equipment such as motors and compressors draw excess current to maintain mechanical output. This increases peak demand and widens the gap between average and maximum load.
By maintaining consistent voltage:
- Motors operate at rated efficiency
- Current draw is more uniform
- Demand spikes are reduced
- System utilization becomes smoother
The result is a higher load factor, meaning your electrical system operates closer to its optimal capacity rather than cycling between underutilized and peak-stressed conditions. In industrial billing structures, improved load factor directly correlates with more efficient use of contracted capacity.
Inductive loads such as motors, transformers, and HVAC systems draw reactive current in addition to real power. While reactive current does not perform useful work, it increases total current flow, contributing to higher I²R losses and increased apparent power (kVA).
Xeco's Line Conditioners actively compensate for reactive current by dynamically adjusting phase relationships and optimizing power flow.
By reducing the reactive component of current:
- Overall current magnitude decreases
- Copper losses in cables are reduced
- Transformer loading is lowered
- Voltage drop across conductors is minimized
This improves system power factor and reduces unnecessary electrical stress without requiring fixed capacitor banks that can overcompensate during low-load periods.
Electrical infrastructure (transformers, switchgear, feeders) is rated in kVA, not just kW. When reactive current and voltage imbalance are present, a portion of that kVA capacity is consumed by non-productive power components.
By stabilizing voltage and reducing reactive current, Xeco's Line Conditioners decrease total apparent power demand. This effectively frees up capacity within existing infrastructure without physical upgrades.
The benefits include:
- Additional load capability without transformer replacement
- Deferred capital expenditure
- Reduced thermal loading on equipment
- Improved headroom for future expansion
In practical terms, facilities can operate more productive equipment on the same electrical system while maintaining safe operating limits.
Each installation is based on a load profile analysis, not assumptions. We recognize that each facility is unique and if measurable inefficiencies do not exist, we do not recommend deployment.
