- Selection Guidelines and Replacement Recommendations
- RVC Series Upgrade: Existing RVC users are recommended to directly upgrade to the corresponding RVC-L model to maintain compatibility of control logic and obtain a longer service life and more stable performance.
- Selection of Number of Circuits: Select the number of circuits based on 1.2 times the total reactive power of the system, and reserve 2-3 circuits for future load increases.
- Control Type Selection:
Stable Loads: Choose contactor switching (Digitare N) for low cost and long service life.
Impact Loads: Choose thyristor switching (Type T) for fast response and no inrush current.
- Harmonic Considerations: If the system THDV > 5%, it is recommended to select a model with harmonic protection functions (such as ABB RVT-L, Schneider NVPL), and use it in conjunction with reactors.
