Using Data Entry Grids and Forms : Working with Records : Working with Rectifier Anodes : Adding Rectifier Anode Information

Adding Rectifier Anode Information
To add a record in the Rectifier Anode Information mini-grid for each anode in the ground bed, follow these steps:
Click the Select ROWs button to open the Select ROWs window (Figure 7-4). Select the pipeline segment(s) with the rectifier you want to work with, then click Save to close the window.
Open the Edit CPDM Data window. Click Data Entry > Edit CPDM Data.
Open the Rectifier Information grid. Click the Information tab and then the Rectifier button .
If you want to collapse the Selected ROWs panel to view more of the grid, click the Selected ROWs bar. Clicking the bar again expands the panel.
Select a row of records in the Rectifier Information grid with the rectifier you want to add impressed anode records. For example, the record for pipeline segment T-1401 with rectifier R-202 is selected in the next figure (Figure 7-107).
If the Rectifier Anode Information mini-grid is not visible, double-click the Rectifier Anode... button to open the mini-grid (Figure 7-107). Click the minimize button in the upper right-hand corner of all other mini-grids to hide these mini-grids.
Click Add in the Rectifier Anode Information mini-grid to add an empty record in the mini-grid.
Type a name for the anode in the Name field. Fields requiring information include a red icon, such as Name shown in the next figure (Figure 7-107).
Enter a value in either the field labeled Impressed Anode Shunt Rating or Impressed Anode Shunt Resistance.
Note: If entering a shunt rating, enter it as a mV per A ratio using the format nn.n/nn.n, such as 50.0/25.0 for the shunt rating 50 mV/25 A. If entering a shunt resistance value, enter the actual resistance of the shunt in ohms. When both of these fields are empty, you can enter a value in the field Impressed Anode Shunt Factor instead. Otherwise, PCS Axis automatically calculates the shunt factor based on the value in the shunt rating or shunt reading field.
Repeat steps 7 through 9 to add each remaining anode in the ground bed.
Click Refresh to update derived fields, such as Number of Impressed Anodes shown in the next figure (Figure 7-107). For more information about derived fields, refer to Working with Derived Fields.
Figure 7-107. Rectifier Anode Information
Note: PCS Axis displays the total number of anodes in the system calculated field labeled Number of Impressed Anodes in the Rectifier Information and Inspection grid. This value is based on the total number of anodes in the Rectifier Anode Information mini-grid. If the field is not present in your grid, refer to Adding a Data Grid Layout Theme to add the field.
