Detailed Behavior

The Availability framework measures Disturbance time from the Sag/Swell module, Uptime from a counter module and meter Downtime from the Diagnostics module. Meter Downtime is added to the Uptime count to provide the total time of observation.

The meter uses three measurements when calculating the availability:

1.Meter Uptime: the time the meter is powered and actively monitoring. The time is measured by counting 1-second pulses from a periodic timer module.

2.Meter Downtime: this time is measured by the meter’s internal clock and made available through the diagnostics module. The diagnostics module downtime register is updated on each power up. This calculation is accurate across a single month boundary: any additional month boundaries are assumed to have 30 days. You must set the Sag limit above the minimum voltage level specific to the power supply and wiring configuration of the meter (see “Sag/Swell Module Configuration” on page 294 for specifications). If there is no control power then it is assumed there is no power anywhere, and this time counts against availability.

When the meter powers up, it takes about 15 seconds before the ION modules are operational again. This power up time counts against the availability (a single power up per year limits total availability to 6 nines). If the application requires better resolution than this, then a UPS or other auxiliary power supply for the meter should be considered.

If the meter or control power circuit is taken out of service for maintenance, you can disable the measurement of meter downtime with ION software; see “Pausing Availability” on page 297.
