Extensive use of non-linear loads leads to excessive 3N-order harmonic currents in the neutral line. In addition, three-phase unbalance and other issues often also cause excessive neutral line current. Excessive neutral line current can easily cause aging and ignition of the neutral line insulation, leading to fire hazards. To address this, our company has developed a new type of neutral line security protector using advanced power electronics technology and control theory, which can effectively eliminate electrical fire hazards caused by excessive neutral line current.
Applications
Suitable for shopping malls, theaters, sports centers, data centers, hospitals and other venues with large 3N-order harmonics, effectively mitigating excessive neutral line current.
