In this video, we will study Introduction to Earthing Families of Earthing Components of Earthing System Methods of Earthing Earth Resistance Measurement of Earth Electrode Resistance and Measurement of Earth Resistivity
To be clear, no voltage is applied by the unit across P1 and P2 as stated at 7:05, these electrodes measure the potential difference in the ground. A voltage is applied across C1 and C2 only.
Thank you very much. I have TN C-S system in my building, and a 3-phase lift motor with control panle in the sixth floor is connected properly to the system as you described and there is encased electrode that is conected to the building structure and to foundation sticking out in the elevator room can I used as earthing for further protection and ground the control panle and the elevator motor to it.
