Grounding resistance is a device that is often used in power industry testing, so how to operate it correctly?

GDCR3000C Grounding?Resistance Tester

1. First, check whether the current line, voltage line and ground network line used for the test are open, whether the rust on the ground pile is cleanly removed, and whether the buried depth is appropriate. At the same time, check whether the connection between the test line and the ground pile is connected. On, please reconnect after processing.

2. The length ratio of the current test line to the voltage test line is 1:0.618, and the length of the current test line should be 3-5 times the diagonal of the ground grid.

3. Connect one end of the current test line and the voltage test line to the instrument according to the regular length and then release them in parallel. The other ends are connected to two ground stakes respectively.

4. Check the test line of the universal grounding resistance tester again, and then officially put it into use after confirming that it is correct.

5. After checking that the connection is correct, connect the power to the instrument and power on the instrument.

6. Press the measurement key to start the measurement.

7. After the instrument displays the test, record the test data.

8. After turning off the power of the instrument, remove the connection, and the test process is completed.
