On an impressed current cathodic protection system, the negative wire of the rectifier is
connected to the:
- Anode
- Cathode
- Drop tube
- Dielectric union
- Cathode 1 / 3
All are examples of acceptable release detection for tanks,
except:
- Impressed current
- Automatic tank gauging
- Statistical inventory
- Soil-vapor monitoring
- Impressed current cathodic protection
cathodic protection
reconciliation
When a tank is temporarily closed, the cathodic
protection system:
- Must be turned off
- Must remain in
- Should be removed
- Operator can have it on
- Must remain in operation
- To prevent static
- To minimize effects of
- To electrically isolate
- To prevent water
- To electrically isolate the tank from the tank gauge 2 / 3

or off.
When a steel tank is installed with a galvanic CP system attached, the tank gauges are usually connected through a riser with a dielectric bushing.What is the purpose of that?
discharge
noise
the tank from the tank gauge
intrusion in the tank
