Impressed Current Cathodic Protection

Working with the leading experts in the field of cathodic protection, Omniflex has expanded its range of monitoring and control and power products to include specialist products for impressed current cathodic protection systems called PowerView CP. This system harnesses our depth of experience in power control and remote monitoring in harsh environments to bring reliable and cost saving solutions to the challenges associated with managing impressed current cathodic protection systems in remote locations. What is CP? Cathodic protection (CP) is a technique to control the corrosion of a metal surface. Cathodic protection systems are most commonly used to protect steel used in structures such as pipelines, storage tanks, steel piles, ships, offshore oil platforms, and reinforcing steel in concrete. The simplest method of cathodic protection is galvanic protection where a metal of different electrochemical potential is used as a “sacrificial” anode, connected to the structure. For larger structures, galvanic anodes cannot economically deliver enough current to provide complete protection. Impressed current cathodic protection systems however use anodes connected to a DC power source to achieve this protection. Many conventional Impressed Current CP systems are built on older phase angle controlled Transformer/Rectifier (T/R) techniques. That technology was well suited to the simpler solutions of decades ago but the problem is, those systems waste energy and have no intelligence, which makes them difficult and expensive to control or monitor. These DC power sources require regular monitoring and adjustment to ensure that they are providing the necessary protection. This ongoing monitoring includes the regular conducting of specialised testing overseen by a cathodic protection expert. Where the structure being protected is remote, this can become very costly. PowerView CP from Omniflex is a field-proven Impressed Current Cathodic Protection System with communications built to the core, providing more efficient system adjustment, qualification and management both on site and by remote access (via Web Browser). Many conventional Impressed Current CP systems are built on older phase angle controlled Transformer/Rectifier (T/R) techniques. That technology was well suited to the simpler solutions of decades ago but the problem is, those systems waste energy and have no intelligence, which makes them difficult and expensive to control or monitor. PowerView Transformer/Rectifiers however are designed using more modern switch mode technology (similar to all modern computer power supplies) which makes them smaller, far more efficient and more accurate. In addition to this, each Powerterm CP Transformer Rectifier has embedded intelligence making it easy to control and monitor remotely. Using technology now standard in over 99% of the world’s most reliable power sources, Powerterm components are designed for typically 30 year life. This power supply technology is field proven, with hundreds of Powerterm devices installed in the field for over a decade. Whether you have an existing Impressed Current CP system, or are planning a new installation, a PowerViewCP solution can reduce your life cycle costs. PowerViewCP is extremely scalable. Whether you operate one system or one hundred systems, management and control of your CP assets will be easier with an Omniflex solution. Some the benefits include: High efficiency T/R’s for reduced power, Regular status reporting by email, Alarm condition alerts by SMS or email, Cloud based long term data storage, Web based condition monitoring, Automated testing and result logging, World-wide system coverage, Monitoring of your existing CP systems.
