Add Rectifier Negative Information

Complete the following steps to add a record in the Rectifier Negative Information mini-grid for each negative wire of a rectifier providing current to a pipeline(s):

  1. In the module's data grid, click the Information tab and then the Rectifier tab.

  2. Select a row of records in the Rectifier Information grid with the rectifier you want to add negative records.

  3. If the Rectifier Negative Information mini-grid is not visible, click and drag the Rectifier Negative Information button at the bottom of the window to the mini-grid area.

    The example below shows the Rectifier Negative Information mini-grid being added to the left of an existing mini-grid in the mini-grid area. Your setup may be different and include none or more than one mini-grids. To replace a mini-grid, move the button over an existing one. To add a mini-grid next to any other mini-grid in the area, move the button to the left or right of the existing one. The border turns orange to show where the mini-grid will be placed.

  4. Click in the Rectifier Negative Information mini-grid to add an empty record in the mini-grid.

  5. In the Add Record window, type a name for the record in the Name field. Fields requiring information include a required icon icon. You must enter information in the required fields before the record will be added.

  6. Click Save to add the record and close the window.

  7. If the rectifier rating is different than the minimum and maximum values provided by PCS in the Negative Current Min and Negative Current Max fields of the Rectifier Negative Information mini-grid, type the rectifier rating in these fields.

  8. Type a value in either the Negative Shunt Rating or Negative Shunt Resistance field.

    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 Negative Shunt Factor instead. Otherwise, PCS automatically calculates the shunt factor based on the value in the shunt rating or shunt reading field.

  9. Click Refresh to update derived fields, such as Number of Negatives.

    For more information about derived fields, refer to Work with Derived Fields.

  10. Repeat these steps to add a record for each remaining negative wire.

    PCS displays the total number of negatives in the system-calculated Number of Negativesfield in the Rectifier Information and Rectifier Inspection grids. If the field is not present in your grid, refer to Add a Data Grid Layout Theme to add the field.
