14.4.6 Virtual Meter

·“Virtual Meters” sum a group of channels / cir-

cuits to provide a single reading that is the sum
of all the circuits. Virtual Meters can be used for
generating:

- Panelboard mains reading without the need

for panel mains CTs.

- Busway end feed monitoring without the need

for CTs in the end-feed.

- Totals for specific groups of circuits on switch

gear to provide system level data.

·Virtual Meters are only available on UMG 804s

with firmware versions 1.126 or higher; all
UMG 804s can be upgraded.

·Virtual Meters share the same numbering group

as True Meters therefore they must not use the
same meter number assignment as any True
Meter.

·Virtual Meters share the same Modbus registers

as True Meters.

Note:

Virtual Meters do not have the following

functionality:

·The voltage assignments and readings are not

active in the Custom Meters section of the point
map. They are still valid in the per channel sec-
tion and show up in the Detail Data web page.

These variables are not active for Virtual Meters:

·Neutral Current
·Current THD Average
·Current Demand
·kW Demand
·Max Current Demand
·Max kW Demand
·KWH Snapshot
·Crest Factor
·Waveform Capture
·Voltage Presence
·Zero current alarm
