The Three-Phase Four-Wire Rack Mount Static Var Generator (SVG) offers dynamic reactive power compensation and load balancing for three-phase 380V four-wire electrical systems. This SVG utilises DSP+CPLD digital control and a three-level topology for precise and rapid compensation, achieving a full response time under 10ms. Designed for standard 19-inch racks, the rack mount configuration provides a space-efficient and robust solution. Available in a range of capacities (15kvar, 35kvar, 50kvar, 75kvar, and 100kvar), this SVG effectively addresses reactive power imbalances and manages neutral currents in four-wire systems.

Features:
● Use DSP+CPLD all digital control core, three-level topology technology, advanced reactive power detection algorithm and PWM control strategy to achieve dynamic and accurate compensation of reactive power.
● Adopt modular design, which facilitates parallel connection of multiple modules, takes small space and is easy to maintain.
● The structural design of independent air ducts and independent warehouses ensures the stable operation of the equipment.
● Carry out full-range dynamic compensation for inductive reactive power and capacitive reactive power, and solve the three-phase unbalance problem at the same time.
● The dynamic response speed to the load is at the millisecond level, which can achieve dynamic and accurate compensation for the reactive power of impact loads.
Applications:
Three-Phase Four-Wire Rack Mount Static Var Generators are ideal for applications requiring comprehensive reactive power control and neutral current management in four-wire systems:
● Unbalanced Load Compensation (Three-Phase): Effectively compensating for unbalanced loads in three-phase four-wire systems, ensuring stable voltage and reducing neutral current.
● Harmonic Mitigation (Four-Wire Systems): Minimising harmonic distortion in four-wire systems, improving power quality and protecting sensitive equipment.
● Data Centre Power Optimisation: Enhancing power quality and stability in data centres with four-wire power distribution systems.
● Renewable Energy Integration (Four-Wire): Supporting seamless integration of renewable energy sources in four-wire systems, maintaining grid stability and power quality.
Three-Phase Four-Wire Rack Mount Static Var Generators provide a comprehensive solution for optimising power quality, managing neutral currents, and improving energy efficiency in three-phase 380V four-wire electrical systems.
