Use a horizontal ground electrode as a loop to protect the soil sensors, for example soil moisture sensors. The loop prevents voltage differences from destroying the sensors and minimizes the effects of continuous ground currents (59/60 Hz hum) to the readings.
- Route the grounding cable from the grounding connector at the mast base to around the mast.
- Bury the electrode, making a 5 … 6 m (16 … 20 ft) diameter loop with the electrode. Guy wires are not needed.
- Make sure the buried loop electrode surrounds the sensors.
- Connect the loop to the mast with two or more connections.
Do not make the wires run parallel any longer than absolutely necessary. |
