CP on Rectifiers

For Cathodic Protection (CP) systems to function properly, they should be inspected, monitored and maintained frequently. For this purpose, a Potentials / Anode Inspections / R/F Inspections section, for capturing CP data during an inspection, can be enabled on the PEI Equipment Details Page (the available sections will depend on the type of Equipment). 

For Equipment of type "CP Rectifier" the CP data can be entered in the Anode Inspections and R/F Inspections Sections. The CP data can also be approved here.

Note: Potentials can be recorded on Equipment of Type "Pipe", "Piping System", "Vessel", and "Tank".

Specifying the Rectifier's Coarse Max & Fine Max

In the Rectifier Equipment's Details section, you can specify the Maximum for the Coarse and Fine tuning setup. To do so:

• Go the Equipment Details Page.
• In the Details section, click Edit.
• Select the Coarse (Max) and Fine (Max) values from the dropdowns.
  Selectin CP values for the Rectifier. 
   
• Click Save.

The values will be displayed in the Specs section where you can also edit them.The Specs.

Anode Inspections

A CP Survey is a detailed assessment to determine the performance of the installed CP system. Included in this Survey is the Current draw (Output) on each Anode, to verify that the Anode is working properly.

Defining Anodes

To add an Anode:

• Scroll to the Anode Inspections section on your Equipment Details Page.
• Click the plus button.

Click + to add an Anode.

• Add a Description.
• Select a Material.
• Click Save.

This way you can define multiple Anodes.

Adding Measurements

To add measurements for the Anodes:

• Click + Add new measurements.

Click the button: + Add new measurements. 

• For each Anode: 
  • Enter the Measurement Date.
  • Enter the Current draw in Amps.
  • Add a Comment if desired.
• Click the Save button.

Note: To see multiple measurements uncheck the Condense dates box.Uncheck to show all measurements.

Viewing the Anode Chart

Click the Anode Chart tab to view the measurements in a chart.

Approving Anode Inspections

When done, you need to approve the Anode measurements:

• Open the Anode Output tab.
• Click the Approve button.

Click Approve.

Note: Whenever you add new data, you will again need to Approve the measurements.

For more information see IMS Approvals.  

R/F Inspections

Also included in this Survey is the Rectifier Current and Voltage input/output measurements (R/F output Amps and Volts).

Adding Measurements

To input a new measurement:

• Scroll to the R/F Inspections section on your Equipment Details Page.
• Click the plus button.

Click the plus button to add a new measurement. 

• Enter the Inspection date (this must be after the Rectifier's Install Date).
• Select the Inspector. By default the current username will be selected.
• Add Comments.
• Add the the Rectifier Current output in Amps.
• Add the Rectifier Voltage output in Volts.
• IMS will calculate the Rectifier Resistance in Ohms.
• Select the Fine tuning. Note: This will be limited by the Fine (Max) spec.
• Select the Coarse tuning. Note: This will be limited by the Coarse (Max) spec.
• IMS will calculate the Adj. Cap (1 max) based on the Fine and the Coarse values.
• Click Save.

Viewing the R/F Inspection Chart

Click the R/F Inspection Chart tab to view the measurements plotted against time.

Approving Anode Inspections

When done, you need to approve the Anode measurements. Each Inspection date requires approval.

To Approve measurements:

• Open the R/F Inspection data tab.
• Select the applicable rows, for the desired Inspection dates.
• Click the Approve button, or click Approve.
  Click the Approve button.

  
  

  
  Click Approve.

Note: Whenever you add new data, you will again need to Approve the measurements.

For more information see IMS Approvals.  

Bulk Importing Inspection Date

You can also import the measurements in bulk. To do so:

• Go to Settings\Data Transfer\Import Data.
• Download the desired R/F Inspections or Individual Anode inspection template.
  Download the applicable template. 
• Fill in the template.
• Select the desired import and click Browse to upload your template.
• The Import Wizard will guide you further.

Export for Import

Alternatively you can also export the R/F Inspections or Anode Inspection data from the applicable sections on the Equipment Details Page, then add the new measurements to the file, and import it back with the import button in the applicable section.
