山东电缆桥架接地电阻的注意事项：

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时分，以及气候、温度、压力等急剧变化时不能丈量。

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、被测地及左近不能有杂散电流和已极化的土壤。

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

4、探测针应远离公开水管、电缆、铁路等较大金属体，其中电流极应远离10m以上，电压极应远离50m以上，如上述金属体与接地网没有衔接时，可缩短间隔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、留意电流极插入土壤的位置，应使接地棒处于零电位的状态。

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、衔接线应运用绝缘良好的导线，以免有漏电现象。

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

7、测试宜选择土壤电阻率大的时分停止，如初冬或夏季枯燥时节时停止。

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