Traditional reactive power compensation device realizes reactive power compensation by adjusting capacitors or reactors. Although it is widely used, it has many problems, such as resonance, slow response and easy damage of capacitors, etc.
Response time: ≤10ms. With extremely short response time, it can quickly track the change of impact load, such as spot welding machine, rolling mill, etc.
MIBF (≥100000 hours), with stable and reliable performance. ZSVG is no possibility of impedance with the system while operating, so it has higher security.
ZSVG can achieve dynamic seamless reactive power regulation from inductive reactive power to capacitive reactive power, and achieve power factor stability to 0.999 or total harmonic distortion of current significantly reduced.
Over-voltage protection, under-voltage protection, over-current protection, over-heat protection, comprehensive control protection, etc.
ZSVG can compensate reactive current and harmonic current, improve three-phase unbalance, suppress voltage fluctuation and flicker, and suppress system oscillation.
