In addition to operating the power supplies a total of seven hundred and twenty (720) reference electrodes are being monitored...

... of the ethanol. Typically, the potential of a metal in an environment of interest is measured against a reliable reference electrode. The reference electrode potential must not respond to changing redox conditions, must be pH independent, chemically resistant, must not release unwanted species into the test...

...It does seem improbable that the reference electrode will provide valid information specifically in the area of interest and particularly when the pipe diameters are large or the pipelines are deep. In each of these cases, there will be many other factors to consider, such as: effectiveness...

... cylinder pipes, pre-stressed and post-tensioned structures), the use of a Linear-Continuous-Reference-Electrode (LCRE) has been proposed, claiming that, once a pit starts in any position on the pre-stressed steel, the potential lowers to values typical of active range, giving promptly the evidence...

.... To measure the potential, fixed reference electrodes (RE) should be embedded within the duct, near the pipe; the measured potential is representative of the corrosion condition taking place nearby. To monitor the potential of the whole metallic structures a series of fixed REs have to be planned...

...The input for the reference electrode is referred to as a ‘High Impedance’ input, which essentially means that a minimum of current flows from the reference electrode into this input. This does not mean that the reference electrode is necessarily a high impedance source, indeed, having a low...

...Abstract The Cu/CuSO₄ electrode (CSE) is typically used as a reference electrode (RE) for monitoring the corrosion protection of pipelines and storage tanks. It requires periodic internal electrolyte replacement due to seasonal wet/dry cycles of soils. It also experiences problems...
