Dynamic Comparison Validation
This validation rule compares measurements to historical statistics for the related Service Point. The system will maintain statistics such as the following: sum, min, max, average, median, zero value count, outage count, and standard deviation. Setting up these
Measuring Component Statistics is a prerequisite to using the rule.
Users can define formulas (no programming required) for the comparison of current measurements to these statistics. This is powerful rule will allow utilities to look for unusual usage patterns. For example:
• Lowest/highest usage ever
• Current usage is more than three standard deviations from the mean
• Detect unexpected zero usage
• Detect negative usage while ruling out known cases
• Abnormal usage
• Voltage threshold monitoring
Note:
Additional detail on the logic of this rule can be found in the Detailed Description of the D2-DYNCOMCHK Algorithm Type.
For help with the meaning of specific configuration fields, refer to the embedded help on the screen when adding or editing the rule.

Example Scenarios
Below are some example scenarios that can be achieved based on configuration of this rule.
Example 1: Detect new "high water mark"
Example 2: High Usage
Example 3: Detect unexpected zero usage (method 1)
Example 4: Detect unexpected zero usage (method 2)
Example 5: Detect negative usage while ruling out known cases
Example 6: Abnormal usage
Example 7: Voltage threshold monitoring
