NACE CP1 Book Chapters 1-4
All electrical connections in ICCP dielectric insulating materials
systems must be completely sealed
with...
Aluminum is an ____ metal, and a amphoteric, -1200
polarized potential more negative
than ____ mVCSE should not be
exceeded
Ammeter measures current flow with resistors (shunts) in parallel
An ammeter is connected in... series
As ions increase, conductivity ____, increases, increases, increases
current ____, and corrosion rate ____
As moisture content increases, increases
corrosion rate...
As oxygen levels increase, decreases, increasing
polarization ____, ____ current
requirements
As pH decreases, corrosion rate... increases
As the anodic area increases, decreases
corrosion rates...
As the relative velocity increases, increases, decreasing
the current requirement ____ due to
____ polarization
, NACE CP1 Book Chapters 1-4
Bacteria (SRB) can have a increasing
depolarizing effect, ____ CP current
requirements
Because the ____ internal resistance low, shunts
of an ammeter impacts current flow,
____ are favored due to their known
resistance value that helps with
accuracy
Cable running to groundbed series, parallel
represents ____ circuit and
groundbed itself represents ____
circuit
The calibration factor of a soil box measured resistance equals resistivity
is 1 - what does this mean?
can handle wide range of advantages of ICCP
voltage/current outputs, satisfy high
current requirements, effective in
protecting poorly coated
structures and in high-resistivity
environments, less anode
consumption
Coating ____ the amount of current reduces
required to protect a structure
