Cathodic protection station

Aapplication

Cathodic protection allows to control corrosion in metal. There are several methods of cathodic protection – galvanic and impressed current. We have designed system that protects pipelines against corrosion using impressed current cathodic protection method (ICCP).

Technical description

Operating mode is automatically selected upon three main limiting set points: reference potential, current and voltage. Control is performed according to one of them, witch is reached first, due to load nature. Other two set points acts as limiting values.

Currently we provide new version of system based on knowledge collected  during sale and maintenance our previous version of cathodic protection station and some innovations in electronic components market.

Station remote monitoring and control software KSC2008:

  • Microsoft.NET based, works on Windows OS.
  • Collects data via GSM modem connection.
  • Allows to monitor (read) or set station output parameters, read data from the station
    internal parameters storage.
  • Data history stored to Microsoft SQL Server or MSDE database (with possibility
    of stored data access from 3rd party tools).
  • Stored station data history may be drawn on the display or even printed.
  • Possibility to connect directly to the station for observing real-time parameters.
