Description

Cathodic Protection Station SOLLICH 1903 CPS is intended for the cathodic protection of metal structures, built on a large area, on its surface, in the ground, in water, with very good insulation in relation to the ground and the environment. In particular, these are all types of pipelines and gas pipelines

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

The CP (Cathodic Protection) Station allows the protection current to be temporarily switched off.

The device allows to switch off the protection current in the cycle Toff/Ton = 2/18, 3/27 or 6/54 [s/s], which allows to evaluate the effectiveness of cathodic protection.

The OK station enables the described task to be carried out automatically, adjusting the operating parameters so as to force the set value of current or potential. The device has the ability to change the operating mode and parameters manually and remotely

Cathodic Protection Station performs measurements of parameters:

  • Ip – the polarization current of the structure.
  • Uak – voltage between anode and construction.
  • Eon – the switch-on potential of the structure
  • Eoff – the switch-off potential of the structure.
  • Uac_on – the effective value of the AC disrupt signals present on the structure.
  • Uac_off – The effective value of the AC disrupt signals present on the structure.
  • E(t) – Measurement of the time course of the construction potential.

Features of the device

  • Operation in galvanostatic mode –mode of current excitation, or potentiostatic mode – voltage excitation
  • Many modes and functions that allow to configure a wide range of applications
  • Programmable setting of current and potential
  • Automatic precision measurements
  • LCD alphanumeric display with backlight, information on the current operating status of the station
  • Cyclic recording of performed measurements in the non-volatile station memory
  • Signaling “Control of the potential range” with colors: green, red and yellow-orange
  • Programming the range of potential control
  • The ability to enable/disable signaling “Potential range control”
  • Generating alarm signals
  • High energy efficiency
  • Remote reading and adjustment of operating parameters, communication with external devices, support for the ModBus protocol
  • Simple installation on a DIN rail, simple commissioning, easy operation
  • Software to read the results from the memory of the station and to set the protection parameters
