4. An auxiliary powered meter is used for applications that require a highly
accurate measurement of power system downtime.
Sag/Swell Module Configuration
Your meter’s power availability framework requires that the Sag/Swell module be
configured to the limits of your meter’s power supply specification. See the online
ION Programmer’s Reference for detailed information on the operation of the
Sag/Swell module.
Operating ranges of the ION 8000 Series meter are listed below:
The ANSI C84.1 1989 standard recommends a Swell limit of 106% for Range B
voltage levels, as well as a Sag limit of 88% for load voltages and 92% for the
service entrance.
