    Product profile


    The CY-D series low-voltage dynamic VAR compensator employs a transistor as the acerous idle-contact switch of multiple-level capacitor set for fast and stepless switching, which overcomes the defects of a traditional device such as easy burning of contacts, easy damage of capacitors and low power factor, presenting satisfying compensation effect for transient impact loads. The three-phase independent control technique employed by the product has successfully solved the technical difficulty of dynamic VAR compensation for three-phase imbalanced impact loads, while the zero current input technology settles the one of easy damage of transistors in harmonic environments under zero voltage input. The dynamic interface of the CY-D series dynamic VAR compensator responses fast (shorter than 20 ms), allowing real-time dynamic VAR compensation that improves the power factor to more than 0.95, reducing voltage fluctuation, suppressing voltage for consumption reduction, and improving the utilization of power transmission and transformation equipment. All of these make this series a new generation of superseding product in VAR compensation field.


    Naming rule



    Notes:

    1. Company code: CEAYEA Electrical &Technology (Shanghai) Co., Ltd.

    2. Product code: low-voltage dynamic VAR compensator 

    3. Rated voltage: 400: 400 V / 690: 690 V

    4. Rated capacity: 400: 400 Kvar 

    5. Series reactance ratio: 7: 7% / 14: 14%


    Tandem reactor of 7% reactance ratio are suitable for load environments of which the primary harmonic number is 5, while the ones with 14% are designed for 3.


    Theory of operation and comparison of technical advantages


    The dynamic VAR compensator, which is also known as the TSC, is a transistor controlling the on and off of the capacitor. Based on the principles, the TSC devices comprise of two types, i.e. the zero-voltage input and zero-current input.
