Our partner "Business TELEKOM" LLC" was a subcontractor in the construction of a DPC in Yekaterinburg. One of the most important elements of a data center is grounding. According to the project, the installation of two circuits at once was envisaged: protective grounding circuit and measuring grounding circuit. The calculated resistance to round electrode current spreading should not exceed more than 4 ohms.

Due to the limited installation area, the only option was to install an electrolytic grounding system. The main element of the circuit is a vertical electrode 9 m long ZANDZ ZZ-100-102-9МВ. 5 electrodes were mounted in total. A copper-bonded GALMAR tape (30x4 mm) was used to connect the electrodes. As a result, the control measurement of resistance showed the result of 0.4 ohms. After the installation, the customer was provided with a protocol for measuring resistance and a passport for the grounding device.
