How a Zero Surge PQ Filter Works

  1. Strong, fast surge current comes from wall receptacle into Zero Surge unit.
  2. The inductor inside our unit acts as a grid, slowing down and decreasing the surge current.
  3. The smaller, slower surge is then sent to a capacitor which acts as a garbage can.
  4. When first capacitor (3) is filled with surge current, any residual current is directed to 2 additional capacitors (garbage cans). This restricts the duration of the surge.
  5. The current is then slowly released to the neutral wire, avoiding any ground wire contamination.
