Figure B.3 – Flicker Record
Note
•
Flicker applied to the device is 10 Pst (nominal voltage 230
VAC).
•
The green line indicates the voltage RMS value and the other 3
lines indicate the flicker Pst values on all the three phases.
Voltage Unbalance
Voltage unbalance is a condition in which the RMS values of the phase voltages or the
phase angles between consecutive phases are not equal.
The level of unbalance is typically monitored from 10-minute average intervals and is
expressed in %.
Unbalance recording complies with the IEC 61000-4-30 standard.
The INFORMA PMD-A
device records the unbalance
at 10-minute intervals and/or user-defined time intervals.
Unbalance data can be stored in the recorder memory where it can be retrieved using the
iQ+ Master Station software.
