VE Mendeleevets - Auxiliary electrode
Auxiliary electrodes VE Mendeleevets are designed for using in the systems of electrochemical protection against corrosion and applied for measuring polarization potential of underground metal construction according to Federal Standard (GOST) 9.602 (method of switching off the auxiliary electrode).
Auxiliary electrodes are used together with copper sulphate reference electrodes of long operation SMES-2.

Auxiliary electrode is a steel electrode 6 with measuring cable 3 installed in the plastic body 5 and sealed with compound. Measuring cable 4 is equipped with cable tip 1 for connection to the control testing station or station of cathodic protection. Auxiliary electrodes are produced in the factory and delivered ready for installation.
There are 4 types of auxiliary electrodes depending on construction:
VE1250 – electrode square 1250 mm2;
VE625 – electrode square 625 mm2;
VE312 – electrode square 312 mm2;
VE156 – electrode square 156 mm2.
