Protection Filters are used on distribution networks which have a high THD (Total harmonic distortion), when the final target is to compensate the power factor at the fundamental frequency.
Its purpose is to avoid overloads due to harmonic currents in the capacitor, deflecting them to the network.
Protection filters are made with serial reactors and capacitors. The tuned frequency of each unit is adjusted between the fundamental and the lower harmonic present in the net, which usually is the 5 th order.
In this way, the filters present high inductive impedance for all the harmonic frequencies.

Schaffner ECOsine™ harmonic filters represent an economical solution to the challenge of load-applied harmonics mitigation in three-phase power systems. With a plug-and-play approach and more compact dimensions than comparable products, they can be quickly installed and easily commissioned. They increase the reliability and service life of electric installations, help utilize electric system capacity better, and are the key to meet Power Quality standards such as IEEE 519.

MTE Matrix Filters solve the problem of harmonic distortion on virtually any kind of six pulse rectifier. These power supplies are commonly found in three phase electronic equipment such as adjustable speed motor drives, welders, battery chargers, servo drives and other equipment.
Harmonics are a problem
Harmonic distortion has become an increasing concern for facility managers, users of automation equipment and specifying engineers alike. Harmonics not only waste energy, but they reduce equipment life, electrical system reliability, system efficiency and equipment productivity.
Guaranteed results
Unlike other harmonic filter technologies, the performance of MTE Matrix Harmonic Filters is guaranteed! On AC variable frequency, variable torque drive applications (fans & pumps), Matrix filters will meet the guaranteed maximum levels of THID (total harmonic current distortion) all the way from no load to full load. Additionally, Matrix filters will not cause power system resonance nor attract harmonics from other non-linear loads. No system analysis is required to select and apply Matrix Filters.
