DCVG Survey: Part 1 - Identifying, Centering & Measuring Coating Defects

This short animation shows the technique to be utilised for a DCVG (Direct Current Voltage Gradient) survey using an analogue voltmeter and matched electrodes.
The video covers the basic methodology in identifying, centering and measuring coating defects (holidays) in the field [OL/RE Potential].
This "How To" guide is intended for asset owners, operators and supervisors that may not be familiar with the technique.
DCVG surveys should always be undertaken by competent and qualified personnel.
Part 2 will address the method necessary to calculate the %IR at Defect, and what this value actually represents.
