Cathodic disbonding tests operating at large cathodic potentials for long periods need current monitoring, pH control and anode isolation

APPLIED OF IMPRESSED CURRENT CATHODIC PROTECTION DESIGN FOR FUEL PIPELINE NETWORK AT NAVAL BASE

Indonesian Navy (TNI AL) is the main component for Maritime Security and Defence. Because of that, TNI AL needs Indonesian Warship (KRI) to covered Maritime area. The main requirement from KRI is fulfilled by demand. To pock of fuel demand from KRI at Naval Base, it needs a new pipeline of fuel distribution network system. The pipeline network system used for maximum lifetime must be protected ...

A review of galvanic anode cathodic protection design procedure

Electrochemistry is a physical science. As a general definition physical sciences apply mathematical equations, making some assumptions in order to predict/explain phenomena/mechanism occurring in the natural environment. The mechanism of cathodic protection in seawater has been covered exhaustively elsewhere and the intent of this paper is to focus on the procedure of the galvanic (sacrificial...

Wireless Remote Monitoring of Cathodic Protection Systems

Chopping effect observed at cathodic arc initiation

Chopping of current and induction of high voltage spikes has been observed at the rising edge of cathodic vacuum arcs. It is argued that current chopping at the rising edge is similar to the current chopping effect that is well-know for the arc current approaching current-zero. Current chopping can generate high voltage spikes, and thus cathodic arc equipment should be protected against voltage...

Bioelectrocatalytic generation of directly readable code: harnessing cathodic current for long-term information relay.

Here we present an exceptionally stable bioelectrocatalytic architecture for electrocatalytic oxygen reduction using a carbon nanotube electrode as the electron donor and a fungal enzyme as electrocatalyst. Controlling oxygen content in the electrolyte enables generation of a directly readable barcode from monitoring the enzyme response.
