4.4.3 Supply Voltage Dips/Swells and Interruptions
The PMC-592 supports the detection of the
Supply Voltage Dip/Swell
and
Interruption
using a method
that is in accordance with Section 5.4 of IEC 61000-4-30 Power Quality Standard for Class A performance
since Firmware V1.00.05. The PMC-592 provides Dip/Swell detection on a per phase basis and can
trigger the following parameters at the same time: WFR, SOE and Alarm Setpoints. The timestamp,
duration and Maximum and Minimum of three phase voltage of each Dip/Swell would be recorded by
PMC-592.
