Ground
Beds
Ground
bed Location should be determined early in the design
process because its location may affect the choice
of grounded type. The following factors should be
considered when choosing a grounded location.
-
Resistivity
- Interference
with other structures
-
Availability of power supply
- Accessibility
- Vandalism
or other damage
-
Purpose of the ground bed
-
Availability of right of way
Conventional
ground beds are normally used to distribute protective
current over a broad area of the structure to be
protected. These are frequently called remote ground
beds because the structure is outside the anodic
gradient of the ground bed caused by the discharge
of current from the anodes to the surrounding structures.
Distributed
Anode Ground beds are used to reduce the potential
for interference effects on neighboring structures.
They are used to protect sections of bare or poorly
coated structure. They are used in congested areas
where electrical shielding might occur with other
ground beds.
