山東電纜橋架接地電阻的注意事項：

1. The grounding line of cable bridge should be disconnected from the maintained equipment to ensure the accuracy of measurement results.

2、下雨后和土壤吸收水分太多的時分，以及氣候、溫度、壓力等急劇變化時不能丈量。

2. When the soil absorbs too much water after raining, and when the climate, temperature and pressure change sharply, it can not be measured.

3、被測地及左近不能有雜散電流和已極化的土壤。

3. There should be no stray current and polarized soil in the measured area and near the left.

4、探測針應遠離公開水管、電纜、鐵路等較大金屬體，其中電流極應遠離10m以上，電壓極應遠離50m以上，如上述金屬體與接地網沒有銜接時，可縮短間隔1/2~1/3。

4. The probe needle should be far away from large metal bodies such as open water pipes, cables, railways, etc. The current pole should be far from more than 10m, and the voltage pole should be far from more than 50m. If the above metal body is not connected with the grounding grid, the interval can be shortened by 1/2-1/3.

5、留意電流極插入土壤的位置，應使接地棒處于零電位的狀態。

5. Pay attention to the position where the current pole is inserted into the soil, so that the grounding rod is in the state of zero potential.

6、銜接線應運用絕緣良好的導線，以免有漏電現象。

6. Wires with good insulation should be used to avoid leakage.

7、測試宜選擇土壤電阻率大的時分停止，如初冬或夏季枯燥時節時停止。

7. The test should stop when the soil resistivity is high, such as in early winter or dry summer.
