Product Introduction

In the low-voltage reactive power compensation system, the capacitor is the core component in the reactive power compensation cabinet. In addition to the impact of the use environment, the life of the capacitor is also very important due to its harmonic current, closing inrush current and long-term overvoltage. Directly cause damage to the capacitor, so a certain proportion of reactors in series in front of the capacitor to suppress and absorb some harmonics and ensure the safety and stability of the compensation loop is the most common method at present.

After the IVL-RE series low-voltage filter reactors are connected in series with capacitors, they can suppress harmonic amplification and filter out a certain proportion of harmonics. After precise matching, they are connected in series with capacitors to form a passive filter, which can accurately filter out certain harmonics. At the same time, it suppresses the inrush current when the capacitor is put in, and protects the capacitor and other components.
