Three-phase harmonic filter reactor 400 V, 12.5 - 50 kvar | RA series

Three-phase harmonic blockREACTOR with high linearity, designed and sized for a high harmonic load and tuned to the capacitors. The RA-type Reactors ensure a lengthy service life, extremely low losses and low noise emission during operation. The CORE of the reactor consists of a magnetic plate made of top-grade iron with low-loss oriented grain with low losses. The WINDING is made with electrolytic copper conductors. IMPREGNATION is done in vacuum autoclave with special resins. The RA-type reactors have a tuning frequency of 189 Hz (p=7%), but other tuning frequencies can also be made on request; of course, in addition to the standard tuning frequency the main ones are 134 Hz(p=14%) and 210 Hz(p=5.67%). USES Especially suited to make modular units (see CTF) and automatic power factor correction equipment (see ERAF) for networks with a harmonic load in association with power factor correction capacitors. With the Capacitors, the RA series three-phase reactors have been conceived and designed to be installed in networks with harmonic distortion since their working principle consists of translating the resonance frequency of the installation under the harmonic of a lower magnitude so as to avoid triggering phenomena of resonance.
