Arc-Suppression Coil
The arc-suppression coil can provide an inductive current to compensate for the short-circuit capacitive current in case of a grounding fault, reduce the grounding current and finally achieve the purpose of arc self-extinguishing, effectively reducing the arc overvoltage.

Product Highlights
Core in-House Development Across the Entire Chain
Core primary equipment, controllers, and key components are independently developed and manufactured, with integrated hardware and software design to ensure system compatibility, reliability, and long-term service capability.
Fast and Precise Arc Suppression
The system starts within 10 μs after a ground fault occurs and completes compensation within 40 ms, limiting residual current to ≤ 5 A to reduce the risks of arc reignition and overvoltage.
Engineered for Decades of Service
High-performance electromagnetic wires, premium insulation materials, and proven structural designs are adopted, with multi-dimensional simulation and type testing to ensure reliable operation under long-term and complex operating conditions.
Transient and Steady-State Integrated Line Selection
Based on the integrated analysis of transient and steady-state signals, the system comprehensively identifies the faulted feeder, improving line selection accuracy and adaptability under complex grounding fault conditions.
