4�2�1�- QUALITY PARAMETERS
Power quality control requires dening the TRMS of the voltage level, subsequently used by
the device to record events. According to the EN-61000-4-30 Standard, the RMS value must
be calculated for all AC magnitudes or each cycle and refresh every ½ cycle. If the RMS value
exceeds certain programmed thresholds, this is understood as an event.
The device detects the quality events, such as overvoltages, gaps, voltage outages and tran-
sients. Figure 30 shows an example of these events.
