Example Standard 15-Cycle Analog Event Report 1/4-Cycle Resolution
look in detail at an example of one cycle of A-phase
current (channel IA) data similar to what is shown in
.
shows how the event report ac current column data relate to the actual sampled
waveform and rms values.
shows how the event report current
column data can be converted to phasor rms values. Voltages are processed
similarly.
In
, note that any two rows of current data from the analog event
report, 1/4 cycle apart, can be used to calculate rms current values.
