1. Bad Energy Data

   1. Description:

      • Find periods for at least a duration when data contains values outside of low and high limits or the data is shown as “not a number” (NaN). Fault dependencies and associated scenarios include the following;
      • All data will be imported into the SCMS ‘as is’ from its existing system.

   2. Requirements

      • Consumption or Demand Point: Any point that has consumption or demand type units

2. Double Dipping Data

   1. Description

      • Finds periods for at least a duration when a point’s history contains two or more data points within a leeway of an interval. Fault dependencies and associated scenarios include the following;
      • All data will be imported into the SCMS ‘as is’ from its existing system.

   2. Requirements

      • Consumption or Demand Point: Any point that has consumption or demand type units

3. Missing Data

   1. Description

      • Finds periods for at least a duration when a record’s history contains zero data points within a leeway of an interval. Fault dependencies and associated scenarios include the following;
      • All data will be imported into the SCMS ‘as is’ from its existing system.

   2. Requirements

      • Consumption or Demand Point: Any point that has consumption or demand type units

4. Sensor Failure

   1. Description:

      • Finds periods over a duration when a sensor does not change by a threshold for a 24-hour period and equipment is running.

   2. Requirements:

      • Sensor: Any numerical data point, including statuses and operating mode(s).
