Harmonic distortion
Current at 150–450+ Hz wastes energy and overheats windings, cables, and transformers.

Energy Savings Cooperation · ESCO
FalconRack™ is a filter-compensating apparatus installed at the site. Zero client capex. Zero maintenance invoice. Guaranteed savings, shared. No redesign of the plant grid.
The hidden bill
Current at 150–450+ Hz wastes energy and overheats windings, cables, and transformers.
A large reactive component reduces useful work from every purchased kilowatt-hour.
Dips, overvoltage, frequency deviation, and phase imbalance stress drives and controls.
Eddy currents and imbalance can leave only about 70% of transformer rating usable.
Up to 30%
Runtime tax on motors and process equipment.
Up to 15%
Internal network loss in cables and windings.
Decades → months
Insulation life under severe harmonic overload.
They raise RMS current and turn purchased energy into heat. The 7th harmonic of 60 Hz is 420 Hz.
| Component | Frequency | Effect |
|---|---|---|
| Fundamental | 60 Hz | Useful working current |
| 3rd harmonic | 180 Hz | Triplen heating in neutrals and transformers |
| 5th harmonic | 300 Hz | Common on VFDs; torque ripple and extra losses |
| 7th harmonic | 420 Hz | Motor overheating and control interference |
| 9th+ harmonics | 540 Hz+ | Insulation stress, capacitor failure, resonance |
The apparatus
01
Free measurement of harmonics, reactive power, imbalance, and load. The guarantee is set from the data.
02
Suppresses harmonic currents so motors, cables, and transformers stop dissipating parasitic energy.
03
Tracks load reactive power, holds power factor, and returns unused capacity.
04
Connects without redesigning the plant grid. Install and commissioning are in the ESCO package.

| Construction materials | Plant | 2023 | 250 kWh | 43% |
| Building-materials plant | Industrial | 2019 | 3,000 kWh | 40% |
| Retail chain | 50 stores | 2022–2023 | 3,000 kWh | 49% |
| Supermarket chain | 11 stores | 2022 | 715 kWh | 43% |
| Light industrial | Plant | 2023 | 145 kWh | 42% |
Odd harmonics dominate. Current does no useful work. Invoices inflate. Transformers run hot. Motors and cables age early.
Harmonics collapse toward a clean sinusoid. Lower RMS current. Less winding heat. Capacity freed inside the existing connection.
