Appendix 2: Major Dip Curves
Your PQube supports the following world-wide standards: STANDARD (IEC 61000-4-34), SEMI F47,
Samsung Power Vaccine, ITIC, CBEMA, MIL-STD 704E, and MIL-STD 1399. These standards define
ride-through curves based on the depth and duration of voltage dips. When the voltage dips
below the ride-through curve, your PQube will trigger a Major Dip event. You can specify which
standard to use in your
Setup.ini
file.
This is especially useful for electrical systems manufacturers, who must design their equipment to
withstand voltage sags that do not dip below the ride-through curve.
7.1.1
STANDARD
NOTE: Use this curve to detect only events that lie outside the SEMI F47 boundary.
