Arteche carries a variety of power quality filters including low pass harmonic filters that attenuate all harmonic frequencies, one phase harmonic filters, tuned filters that attenuate specific harmonic filters and active harmonic filters. Arteche also offers PWM voltage sine wave dv/dr filters.
Arteche tuned harmonic filters divert harmonic energy away from the power source (which is common to other loads) and localize the flow of harmonics to that part of the electrical system which is between the harmonic producing load and the filter. Their automatic (switched) harmonic filters are able to measure the power factor and harmonic distortion for a system and use contactors to switch multiple filter networks into or out of the circuit. This maintains acceptable harmonic distortion without over compensating the power factor. Arteche also offers a dynamic response harmonic filter that are similar to the automatic harmonic filters except switching is accomplished by the use of Thyristor technology as opposed to electromechanical contactors. This enables the filter to be inserted into the electrical system in as little as one-half cycle (8-10 milli-seconds).
Arteche instrument transformers are made for both outdoor and indoor service. The former include oil-paper insulated, gas-insulated, inductive voltage, capacitative voltage, and many other types of transformers. By contrast, indoor transformers are divided by low and medium voltages; these include toroidal types for primary nominal currents up to 10A, rectangular window types up to 3A, and auxiliary transformers up to 200A, as well as window- and support-type units that provide 3.6kV to 24kV insulation voltage. Other related products include support resin-cast insulators, signal insulators, and wall bushings for insulation levels up to 36kV.
