Description

The SOLLICH 2003 CATHODIC PROTECTION STATION is designed for cathodic protection of metal structures built on a large area, on its surface, in the ground, water, with very good insulation in relation to the ground. In particular, these are all types of liquid and gas 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 cathode -/K and the Ku terminal are connected to the protected structure.

The OK (Cathodic Protection) Station allows for temporary switching off of the protection current.
The OK Station allows for the implementation of the described task automatically by adjusting the operating parameters in order to force a 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 – structure voltage.
  • Eon – structure switching potential.
  • Eoff – structure shutdown potential.
  • Uac_on – Effective value of AC interference signals occurring on the structure.
  • Uac_off – Effective value of AC interference signals occurring on the structure.
  • E(t) – Measurement of the time course of the structure potential. “Oscilloscope” mode

The SOLLICH 2003 CPS station requires a DC power supply with parameters depending on the version.

  • version: 24-300 (Us = 12 … 28V; Ip_max = 300 mA)
  • version: 24-600 (Us = 12 … 28V; Ip_max = 600 mA)
  • version: 24-1000 (Us = 12 … 28V; Ip_max = 1000 mA
