ER-XHG1 overvoltage suppression cabinet

The ER-XHG1 overvoltage suppression cabinet is an automatic control system composed of intelligent control, overvoltage limiting technology, and single-phase switches. Using instantaneous changes in system parameters and short circuiting of PT open delta windings on the busbar to eliminate resonance; By limiting the amplitude of the recovery voltage of the faulty phase and the rising speed of the recovery voltage, arc grounding is eliminated; By increasing the zero sequence current of the fault line for a short period of time and enhancing the selectivity of grounding protection, the fault line can be accurately located and disconnected. Advanced technology and reliable operation.
