Trends

The device records and displays the average of the system insulation in form of curves. The device displays curves as per the following durations:

  • last hour (1 point every 2 minutes)

  • last day (1 point per hour)

  • last week (1 point per day)

  • last month (1 point per day)

  • last year (1 point per month)

The chart scale automatically adjusts to the shown data to optimize the display accuracy.

The curves show a general trend how the system insulation evolves over time. They are calculated from averages related to shorter or longer durations depending on the charts. So charts may not show transient insulation faults when they are smoothed over time.
