Active filter technology is the most advanced approach for mitigating harmonics. Fast current detection and micro-controlled inverse current injection reduce total harmonics to less than 3% THDi.
Highly efficient
Active filters operate on much lower currents than comparable serial methods and are much more efficient. Dimensioning to the individual harmonics spectrum requirements saves further costs.
Flexible
Active filters support central, individual or group compensation set-ups.
