Technical specification:
Product Features:
• Tracking the changes of the reactive load of the system by the controller, taking the power factor and reactive power as criterion, switching automatically and reasonably, lessening the switches, avoiding the problem of switching vibration and reactive power delivery. Thus, the power factor of the system can keep in optimum conditions. The switching mechanism is optional, there are 3 ways to choose from, contactor switching, SCR switching, and load switch switching, you can choose one of them to meet the requirements of switching mechanism in different power grid environments
• With operation mode of muti loop switching, which effectively avoids the problem of too frequent switching of individual capacitors during packet switching. Automatic fast tracking of reactive power changes to achieve optimal control
• Power saving effect is obvious, the power factor can be increased to more than 0.9 Multiple compensation modes: Three-phase common compensation, three-phase dispersion compensation, common compensation+dispersion compensation. Choosing the compensation mode reasonably according to the actual situation of the power grid, and taking the effect and cost of compensation into account. Fully resolve the contradiction between the reactive power compensation and the three-phase imbalance, as well as the contradiction between the three-phase separate compensation and the cost. Adopting the three-phase common compensation mode, of which the effect is good and the cost is low, for the three-phase basic balanced system. For the three-phase seriously unbalanced system, the mode of three-phase separate compensation is adopted to effectively solve the problem of over-compensation and under-compensation, the cost is higher. As for the three-phase slightly unbalanced system, using the mode of the common compensation+dispersion compensation, to avoid the problem of over- compensation and under-compensation, and the cost is relatively low.
