Technical and Application Notes
The ZT-830 controller performs comprehensive calculations on voltage, current, power factor, and reactive power. The voltage return difference participates in the control judgment to make compensation more accurate and prevent switching oscillation. Multi-contact sampling within the action delay time judges reactive power trends to avoid errors caused by single-contact sampling.
Model Selection: ZT-830GB is designed for three-phase simultaneous compensation, while ZT-830FB supports both simultaneous and phase-splitting hybrid compensation modes. Choose the appropriate model based on your reactive power compensation requirements.
Typical Applications
- Reactive power compensation systems
