Petersen Coil

Equipped Petersen coil systems can compensate for the capacitance of the line current, the single-phase ground fault current flows through the capacitor grounding point for the minimum point of the arc of a reliable ground fault arc , to avoid reigniting , prevent arcing ground fault point phase faults caused by short circuit . But will also prevent the neutral point displacement due to different switching operation of single-phase disconnection caused by other factors , to avoid the neutral point voltage is too high, the threat of insulation safety equipment . In addition Petersen coil in the normal operation of the power grid , and can effectively prevent resonance over-voltage , prevent equipment damage caused thereby , better protection of system security , stability, and high-quality operation. Automatic tuning arc suppression coil can meet the common good basis to eliminate the role of the Petersen coil grid resonance occurs , install and use the effect is significant.
