Author: Jim Walton

Publication Date: 2017

$20.00

This paper will point out when and why to use either Direct Current Voltage Gradient (DCVG) or Alternating Current Voltage Gradient (ACVG) surveys, including what the criteria of percent IR and Decibel microvolt (dBµV) really mean when conducting these survey techniques.

Benchmarking International Cathodic Protection and Alternating Current Mitigation Standards to Determine Suitable Protection Criteria

Product Number: MECC23-20206-SG

Author: Craig Botha

Publication Date: 2023

$20.00

The past 20 years in the field of Cathodic Protection (CP) have ushered in the distinct shift from the assessment of conventional Direct Current (DC) corrosion mechanisms to the more complex world of electrochemistry influenced by Alternating Current corrosion mechanisms. In fact, traditional assessment of CP protection levels without taking cognizance of the AC interference on a structure can have catastrophic consequences for pipeline operators. The most common misnomer over the past 20 years has been the idea that a pipeline under suitable levels of CP cannot corrode in a High Voltage Powerline Right of Way.
