Rustrol® Systems, DC-Decoupler™
Interprovincial/International Corrosion Control manufactures Rustrol® Systems for World Wide Distribution. The Rustrol® solid-state DC-Decoupler™ Model: DCD are an essential component for safely isolating cathodically protected structures (i.e. Pipelines, On-Grade or Buried Storage Tanks, etc.).
Rustrol® DC-Decoupler™ Model: DCD device is designed to protect personnel and equipment from electrical disturbances. The DC-Decoupler™ Model: DCD blocks DC current associated with cathodically protected structures, and provides an effective and continuous conductive path to the Utilities Grounding/Earthing Network for all other forms of Electrical Exposures, such as:
- Lightning/Surge Currents
- AC Fault Currents
- AC Induced Voltages
- Over-Voltage Protection.
The Rustrol® DC-Decoupler™, Model: DCD enhances the Rustrol® Product Line by providing economical alternative for light/moderate (i.e. non-continuous) exposure of Lightning, AC Mitigation/Discharge and AC Fault Current.
The Rustrol® DC-Decoupler™ Model: DCD is a recent development to the Rustrol® Product Line. The DC-Decoupler™‘s unique features are based on the proven Rustrol® technology utilizing solid-state design and superior test proven, quality components throughout the construction. The standard DCD Product Line provides an economical engineered solution in a compact, lightweight, ready to mount assembly.
The Rustrol® DC-Decoupler™ Model: DCD is innovative by design, whereby DC isolation is achieved and AC coupling is maintained, ensuring electrical grounding criteria remains effective.
The Rustrol® DC-Decoupler™ Model: DCD is capable of reducing the potential difference across isolating flange assemblies and/or monolithic isolating joints to well below the industry accepted criteria (i.e. <10 volts AC rms).
The Rustrol® DC-Decoupler™ Model: DCD is versatile and can be used in numerous applications, including coupling the primary structure (i.e. pipes, valves, pumps, etc.) in series through the DC-Decoupler to Gradient Control Systems.
The Rustrol® DC-Decoupler™ Model: DCD is typically utilized within:
- Oil and Gas Transmission Pipelines
- Refinery and Petrochemical Industries
- Electrical Utilities
- Tank Farm/Oil Depot Facilities.
