Validating Register Constants

You can validate the register constants of all installed electric meters, by service cycle (the service cycle of the service points in which the meters are installed). This allows you to check and confirm, in mass, the entered constants for all meters.

This background process (REGCNST) selects all electric service points on the input service cycle. It uses CT (current transformer) and PT (potential transformer) equipment linked to SP to calculate register constant using the formula:

Calculated Register Constant = Product of all CT, PT ratios * Dial Constant

If the calculated register constant doesn't match to the actual register constant, a To Do entry is created.

In order for the process to know how to find the correct equipment and the correct ratios, control tables need to be set up appropriately and parameters for the background processes need to be defined accordingly.

• Equipment is set up through the use of Items. You will define an Item Type to be used for CT equipment and another to be used for PT equipment.
• The CT Ratio will need to be defined using a Characteristic Type for the CT Item.
• The PT Ratio will need to be defined using a Characteristic Type for the PT Item.
• The Dial Constant will need to be defined using a Characteristic Type for the Meter.

In order for the background process to work correctly, the following input parameters will need to be populated:

• Service Cycle
• Item Type to identify the CT Equipment
• Item Type to identify the PT Equipment
• Characteristic Type to identify the CT Ratio
• Characteristic Type to identify the PT Ratio
• Characteristic Type to identify the Dial Constant
• To Do Type and To Do Role
