Question 1
A CP technician observes that a rectifier has been providing stable DC output for months, but in the past week the DC output current has risen by 30% with no voltage change. Which cause is MOST likely?
Correct Answer:
New coating holiday or increased CP demand on the structure
Question 2
Which technique does a CP Technician use to locate small coating defects along a pipeline without excavation?
Correct Answer:
Direct Current Voltage Gradient (DCVG) survey
Question 3
During an instant-off survey on a pipeline with two rectifiers, both interrupters are synchronized and run for one full cycle. The 'on' potential at test station TS-15 is -1.080 V CSE and 'off' is -0.840 V CSE. What should the technician report?
Correct Answer:
The polarized potential does NOT meet the -850 mV polarized criterion; additional CP current or investigation is required
Question 4
Which of the following is MOST likely to cause static DC stray current interference on a buried pipeline?
Correct Answer:
Another pipeline's operating CP rectifier nearby
Question 5
A pipeline crossing a high-voltage AC transmission corridor shows 45 V AC induced voltage at a test station. Per NACE SP0177 personnel safety guidance, what action should the CP Technician take?
Correct Answer:
Stop work, mitigate induced AC to below the 15 V AC personnel safety threshold (or apply approved protection practices), and notify supervision
