Three-phase imbalance automatic regulation device was developed after many years' hard work of our company.
Because there are many single loads in the apartments and rural power grids and there are randomness and asynchrony when loads are connected to the power grid, so the distribution transformer will be the status of asymmetric operation. Using YDK-SPC will make the three-phase loads to be balanced as much as possible.
Equipping YDK-SPC Three-Phase Unbalanced Management Device can improve the power quality of courts greatly.
* YDK-SPC can solve the distribution three-phase imbalance thoroughly and reduce the low-voltage distribution line loss observably.
* YDK-SPC can make the reactive power to be balanced on the spot and improve the power factor of distribution.
* YDK-SPC can improve the power quality, steady the system voltage, improve the distribution quality and improve the power environment.
* YDK-SPC can perfectly solve the transformer overload operating which is caused by the three-phase imbalance so that transformers can have the longer service life.
Multiple Protection Function
* Adopts the double DSP and FPGa controlling system which can make the controlling system to get the better reliability and anti-interference performance.
* Adopts the modular design which can expand the capacity by adding modules in parallel. And users do not need to equip the additional secondary CTs.
* Adopting the independent air glues design and intelligent heat dissipation controlling technology can make the cooling fans running in different rotate speeds which is decided by the device's status - standby or running.
* Lengthen the service life and keep the heat dissipation performance.
Superior Compensating Efficiency
* Realize the dynamic regulation and compensating so that the response time will be less than 10 ms.
* Adopting the advanced three level topology construction makes the output waveform to be closer to the sinusoidal waveform which can reduce the switching loss observably.
* Adopting the flexible grid connection technology reduces the impact to the equipment in the power grid and improves the system reliability.
