Understanding the basic challenge of harmonics specific to your power system is the first step in the process of choosing the right harmonic mitigation filters. Total harmonic distortion should be assessed and measured because such measurement aids in determining the type and size of the harmonic filters needed. Other factors like load conditions, system design and regulatory requirements are also very important in the process of selection. These parameters will be analyzed by the experts in Sinotech Group and the best alternatives appropriate for the operational environment will be suggested.
