Cathodic protection issues of oil tanks
Thread Content
Bro, I’m facing some issues right now and would like to ask for some advice here regarding cathodic protection for oil tanks. How to use a multimeter to measure potentials such as those related to the cathodic protection of oil tanks, the potential of the ground, and the potential of the reference electrode? Please provide detailed instructions, as this is my first time doing this and I am not very familiar with this topic.
During the study*, we all look forward to the professional opinions of experts.
Can a multimeter measure the potential of an oil tank? Learn* it a bit.
Prepare a calomel electrode and a digital multimeter. Insert the calomel electrode into the soil, and measure the potentials of both the reference electrode and the device with respect to the calomel electrode. All cathodic protection systems have several dedicated test piles, which contain test points for these two potentials. By entering these potentials into a record sheet or drawing a potential distribution graph and comparing it with the ideal potential distribution graph and potential values, it is possible to determine whether the protection is functioning properly and whether there are any issues with the reference electrode.
I’m using a zinc reference electrode now; how should I use it?
