Probability Display (for Quasi-stationary or Fluctuating harmonics)
The Probability display shows the cumulative failure probability (or percentile) of the quasi-stationary or
fluctuating harmonic data for the entire test.
Note: If no data appears in this display, go back to the Test window and press the Run Post
processing button to generate the probability data.. Probability calculations are
performed from all of the test data.
The following data is presented for each of the 40 harmonics:
ñ the mean in amperes and as a percent of the regulation’s limits for each harmonic.
ñ the standard deviation of each harmonic in amperes and as a percent of the regulation’s limits.
ñ magnitudes for the 50th, 90th, 95th, 99th, and 100th percentiles in amperes and as a percent of
the regulation’s limits.
Failures are indicated in red and are enclosed in brackets. When the data is sent to a printer, failures are
enclosed in parentheses. Color printers will also print errors in red.
