Product overview

The extensive use of modern power electronic devices generates nonlinear currents that affect thepower grid in a harmonic manner, exacerbating grid pollution and causing overload and failure otcapacitors, transformers, and transmission equipment. This causes serious interferenceresonance,and voltage distortion to measurement, transmission, calculation, and othelequipment, leading to power supply accidents. Series reactors can be improved and avoidedAfter connecting capacitors in series with reactors, the resonant frequency is lower than the lowestin the system (usually 5th and 7th), making it capacitive at power frequency to improve powerfactor. In resonance, there is no filtering of amplified harmonics, and after good impedancematching, the capacitor bank can absorb 30% -60% of harmonic current (such as 5th).

Product Applicatior

· lmprove the distortion ofinput current waveform caused by capacitor filtering;

· Reduce and prevent damage to rectifier bridges and overheating of capacitors caused bysurge currents:
· lmprove power factor and reduce DC bus AC pulses;
· improve the transient voltage of the power grid:logether with capacitors connected inparallel, suppress or filter out DC ripple to eliminate adverse effects on the load
