The electrode length (construction length) according to the Hokuden EP-1 standard construction method can be calculated from the grounding resistance value (Ω) of the grounding rod (grounding rod).Calculation procedure1.
Enter the target valueExample: If class A is 10Ω or less, enter a provisional value of 8Ω.2.
Input of measured valueEarth rod (ground rod) 14 x 1500 mm 1 measured value* If the length of the electrode is long, measure at multiple points.* The electrode length (construction length) obtained from this computer is a provisional value calculated by simple calculation.* The electrode burial depth is based on GL-75 cm or more.
