Low voltage electrical reactor in series

Pure capacitor compensation devices are frequently influenced by harmonic current, switching surge and over-voltage in reactive compensation circuits, and capacitors are easily damaged. Therefore some electrical reactors are connected in series to inhibit and absorb some harmonics, and to improve reliability and stability of power supply system significantly. In most cases, if harmonic content of a grid is too high, electrical reactors compatible with the capacitor must be connected in series.

Anderson Wright refines electrical reactor design by dedicated design software, and provides customers with tailor-made products. Iron core of electrical reactors is made of pressed and overlapped high-precision silicon steel sheet to avoid inductance difference between the three phases and ensure tuning precision of the electrical reactors. In addition, in a power grid environment with serious harmonic pollution, sufficient iron core linearity may withstand repetitive switching of capacitor groups and prevent saturation.
