Selection guide
Assessment of harmonic pollution level of the system
- Modern power systems increasingly use nonlinear loads (inverters, LEDs, computers, etc.), generating harmonics. Harmonics directly affect the efficiency of reactive power compensation and the stability and reliability of the compensation system in a power disturbance environment. How to assess the level of harmonic pollution
- Based on the ratio of total nonlinear load capacity/power transformer capacity
- Harmonic index THDi, THDu
Select compensation configuration
- Centralized compensation: Applicable to systems with evenly distributed loads and short distances between loads
- Distributed compensation: Suitable for systems with many large individual loads and long distances from source to load
- Combined: Combining centralized and distributed compensation to optimize operating efficiency in complex systems.
Special options
- Use thyristor switching if the system requires fast response, instantaneous compensation
- Choose 14% reactor when the system has high 3rd harmonic ratio, to avoid resonance and protect capacitors
