Proven results across sectors
The same assess–correct–confirm approach, applied across different industries and load types — each outcome verified on independent instruments.
PFC and harmonic correction for textile manufacturing
Challenge
Very high harmonics and poor power factor. Voltage distortion exceeded the 8% limit and total demand distortion (TDD, IEEE 519) exceeded limits at both incomers during the investigation, resulting in frequent equipment failures.
Solution
A custom active harmonic filter system to remove harmonic currents and correct power factor, bringing the network back within standard limits.

Power-factor correction & harmonic filtering for FMCG packaging
Challenge
Fast-changing injection-moulding loads that conventional capacitors could not follow, with high harmonics causing repeated capacitor and fuse failures and elevated demand charges.
Solution
A combined static var generator and active harmonic filter system sized to a rapidly fluctuating load of around 2 000 A, with the result confirmed on the installed 4G power meter.
Verified results
Detuned-reactor correction across three substations
Challenge
No correction in place across three transformers, giving very poor power factor, high maximum demand and costly reactive-energy charges.
Solution
Detuned-reactor power-factor correction installed at all three substations to lift power factor, reduce demand and cut reactive charges — confirmed over the first month of operation.
