Energy & Demand Calculations
The Energy & Demand diagram shows the real-time sliding window demand for
kW, kVA and kVAR, and the real-time energy values kWh net, kVARh net and
kVAh. Peak demand is displayed for kW, kVAR and kVA, and a link to a demand
profile trend is provided. Control objects for enabling/disabling demand logging
and resetting energy and demand values are also included.

imported, exported and net energy
Demand, Energy and Peak Demand Reset
Level 3 WinPM.Net authority is required to reset these values.
Demand Profile Trending
The Log Server must be running to view the energy and demand log. Energy and
demand logging is enabled by default. Level 3 WinPM.Net authority is required to
use the enable control object. The control object indicates the logging enable status:
the switch is in the up position (1) when logging is enabled, and down (0) when
logging is disabled.
Over Average Current Monitoring
Over current monitoring is disabled by default. Level 3 WinPM.Net authority is
required to enable this monitoring. Each status reads “Not Available” when
monitoring is disabled.
Under Average Voltage Line-to-Line Monitoring
Over voltage monitoring is disabled by default. Level 3 WinPM.Net authority is
required to enable this monitoring. The status reads “Not Available” when
monitoring is disabled.
Under Power Factor Monitoring
Under power factor monitoring is disabled by default. Level 3 WinPM.Net
authority is required to enable this monitoring. The status reads “Not Available”
when monitoring is disabled.
Digital Inputs
The Digital Inputs diagram monitors the four status inputs on the 9300. The status
of each input (ON or OFF), and the number of times the status has changed is
displayed. The status change counter can be reset.

Status change counter for each input
Status
The 9300 meter’s status inputs are de-energized when the meter is powered-up, so
each status will initially be OFF.
Reset
Level 3 WinPM.Net authority is required to reset the status counter.
