Introduction to the Working Principle of BY96-SPC/140kvar-0.8/3L-W
Through the example in the figure below, it can be seen that the load current of phase C is the highest.and there is no load on phase AB. At this time, if there is no SPC, the three-phase currents on the grid side are A0, B0, and C90, which are directly sent from the substation to the load side. Now an SPC devicehas been added to achieve three-phase current balance on the grid side. The device absorbs 30Acurrent from phase A and 30A current from phase B. Through the AC-DC-AC transformation of thecurrent, the excess energy of phases A and B is supplied to the C-phase load with high energy demand.In this way, the grid side senses changes in three-phase current, and phase A outputs more than 30A:B-phase multi output 30A: The output of phase C is 60A less, achieving the goal of evenly balancing thethree-phase current transmitted to the transformer over this distance.
Function Introduction of BY96-SPC/140kvar-0.8/3L-W
Prevent Central Line Overload & Fire Hazards with Intelligent Load Balancing
- The BY96-SPC dynamically redistributes phase currents in real-time, eliminating overload risks caused by unbalanced loads. This reduces line heating, prevents insulation aging, and minimizes fire hazards from central line burnout. Integrated thermal monitoring ensures compliance with industrial safety standards, ideal for manufacturing plants and high-power facilities.
Neutral-to-Ground Voltage Stabilization for Weak Current Systems
- By correcting zero-sequence currents, the device suppresses neutral-to-ground voltage surges (up to 80% reduction), protecting sensitive equipment like PLCs, IoT controllers, and medical devices from damage due to voltage spikes. This is critical for data centers and laboratories relying on low-voltage precision systems.
Voltage Imbalance Compensation to Eliminate False Alarms
- Proprietary algorithms detect and neutralize voltage imbalances (≤1% deviation), preventing false triggers in voltage-sensitive equipment such as relays and sensors. This enhances operational continuity in sectors like renewable energy grids and automated production lines.
Transformer Efficiency Optimization via Single-Phase Overcurrent Suppression
-
The device limits single-phase overcurrents by redistributing reactive power, reducing transformer losses by up to 15% and extending lifespan. This supports energy-efficient transformer operation in commercial complexes and utility substations.

Application Scenarios of BY96-SPC/140kvar-0.8/3L-W Series Three-Phase Unbalance Correction Device
Industrial Manufacturing Plants：The BY96-SPC device is critical in industrial plants where heavy machinery like CNC machines, induction motors, and variable frequency drives generate harmonic distortions and three-phase imbalances, leading to energy waste, equipment overheating, and costly downtime. This high-voltage correction system automatically balances phase currents in real time, reducing neutral line overload and preventing transformer overheating while stabilizing voltage levels within ±5% tolerance. It suppresses harmonics (up to 30kvar capacity) from nonlinear loads, improving power factor compliance with IEEE standards and cutting line losses by 15% to support industrial sustainability goals. Ideal for factories requiring three-phase imbalance solutions, industrial harmonic filters, or high-voltage reactive power compensation systems, it ensures operational reliability and energy efficiency.
Renewable Energy Integration (Solar/Wind Farms)：In solar farms and wind turbine installations, intermittent energy generation from inverters often destabilizes grid-connected power quality by injecting harmonics and creating phase imbalances. The BY96-SPC device enhances grid stability by correcting voltage fluctuations (300–480V input range) and balancing three-phase currents for seamless grid synchronization. It neutralizes high-frequency harmonics from inverters, maintaining Total Harmonic Distortion (THD) below 0.2% to meet strict grid compliance standards. Additionally, its reactive power compensation optimizes power factor to 0.8, minimizing utility penalties and maximizing energy export efficiency. This makes it a vital solution for solar farm voltage stabilizers, wind turbine harmonic suppression, and reactive power compensation for renewables.
Commercial High-Rise Buildings & Data Centers：Commercial high-rises and data centers face power quality challenges from high-density IT loads, HVAC systems, and elevator operations, which cause phase imbalances and harmonic pollution. The BY96-SPC device distributes electrical loads evenly across phases to prevent overloading, extending equipment lifespan through RS-485 communication for real-time monitoring. It protects sensitive IT infrastructure like servers and UPS systems from harmonic-induced voltage sags or swells, ensuring 99.9% uptime for critical operations. With IP54-rated protection and built-in overload/short-circuit safeguards, it aligns with data center redundancy requirements and addresses needs for data center power quality optimization, commercial building phase balancers, and harmonic filters for HVAC systems.
