We measure first. Then we choose the equipment.

Reactive power compensation and harmonic filtering for industry. The solution is chosen from the measured load profile and its economics — not from a manufacturer's catalogue.

Solution lineup

Power quality measurement
Load profile · harmonics · peaks · event logging

Every solution starts with on-site measurements. The report comes with conclusions and payback figures, not just graphs.

Automatic capacitor banks
50–300 kVArAutomatic compensation

The standard solution for stable load profiles.

Hybrid units
Contactor + thyristor switching

Speed where it's needed — economy where it isn't.

SVG — static VAr generators
30–400 kVArResponse <10 ms · cos φ >0.98Per-phase compensation

For dynamic and unbalanced load profiles.

APF — active harmonic filters
30–150 AHarmonics 2–50

Harmonic filtering for converter and VFD environments.

ACS/DVR — voltage quality units
Range selected from the measured site profile

Real-time compensation of voltage sags, fluctuations and flicker.

02 · CASES

Problem. Solution. Result.

VIGO Engineering
65.3% → 10% THDi
PROBLEM

THDi of 30.6% and 65.3% on two feeders. Equipment overheating, protections tripping without cause.

SOLUTION

600 A active harmonic filters on two feeders — sized from the measured profile.

RESULT

THDi around 10% on both feeders. Followed by a solar plant before the factory opening.

Nemuno banga
2 × 180 kVAr hybrid
PROBLEM

Reactive power charges and unstable compensation.

SOLUTION

2 × 180 kVAr hybrid compensation.

RESULT

Reactive power charges cut by up to 97%. The engagement grew into full electrical infrastructure maintenance.

Grigeo Tissue
22 × 200 A AHF · 4,400 A
PROBLEM

High-power production lines generating harmonics beyond what single filters can cover.

SOLUTION

22 active harmonic filters of 200 A each in one system.

RESULT

4,400 A of active filtering — our largest implemented filtering scale.

Umaras
650 kVAr SVG · 4 feeders
PROBLEM

Four independent feeders with different load profiles.

SOLUTION

650 kVAr of SVG compensation distributed across four feeders.

RESULT

Each feeder controlled independently — a complexity case.

Eternit Baltic
A hybrid from the existing system
"Not everything old needs replacing."
SOLUTION

The old contactor cabinets stayed — SVGs were integrated into them. The system became hybrid.

RESULT

The required result at a lower cost.

Steka
PF 0.7–0.8 → close to 1
PROBLEM

Power factor of 0.7–0.8, reactive power peaks up to 400 kVAr.

SOLUTION

Compensation sized from the measured load profile.

RESULT

Power factor close to 1.

03 · HOW WE WORK

Six steps

01
On-site measurements

Free audit for sites in Lithuania — measurements within 5–10 working days of your request.

02
Data analysis

Load profile, harmonics, peaks, tariff structure.

03
Solution and economics

We present the payback period in numbers, for each specific site.

04
Equipment selection

From the measured profile — not from a single manufacturer's catalogue.

05
Installation and start-up

With minimal disruption to production — including live-site work.

06
Monitoring and maintenance

Monitoring, periodic measurements, maintenance contracts.

A free power quality audit at your site.

We reply the same day and measure on site within 5–10 working days. Sites in Lithuania, no obligations.
