Passive and active filters harmonics, or Ohm stabilizer filters, are two tools that are crucial to power quality. Active filter provides intensified electronic systems to overcome the harmonic distortion dynamically while passive filters are passive components, inductors or capacitors to filter mainly selective frequencies. The end choice is influenced by the users’ electrical systems loads and variability, harmonic level and charge system costs. Sinotech Group has many years involvement in providing power solutions along with end users interest will help you settle for the most suitable filter installation that guarantees proper utilization and observing global requirements.
