Description

Cathodic Protection Station SOLLICH 2103 CATHODIC PROTECTION STATION is designed for cathodic protection of metal structures, built locally as well as in a large area, on its surface, in water, with good insulation in relation to the ground. In particular, these are all kinds of liquid and gaseous fuel tanks, pipelines and gas pipelines.

The Cathodic Protection Station works in a three-electrode system with a reference electrode or in a two-electrode system without this electrode. The -/K cathode and the Ku terminal are connected to the protected structure.

The OK station (Cathodic Protection) enables temporary switching off of the protection current.
The OK station enables the implementation of the described task in an automatic way by adjusting the operating parameters so as to force the set value of current or potential. The device has the ability to manually and remotely change the operating mode and parameters.

The Cathodic Protection Station measures the following parameters:

Ip – structure polarization current.
Uak – anode voltage – construction.
Eon – switching potential of the structure.
Eoff – the structure’s shutdown potential.
Uac_on – RMS value of AC interference signals occurring on the structure.
Uac_off – RMS value of AC interference signals occurring on the structure.
E(t) – Measurement of the structure potential time course. “Oscilloscope” mode.

The SOLLICH 2103 CPS station requires a DC voltage supply with parameters depending on the version
execution.
