3.1.1 The Prometer 100 meter in an energy management system
You can use Prometer 100 meters as standalone devices, but their extensive capabilities are fully realized when
used with software as part of an energy management system (EMS). EMS gives energy suppliers, service
providers, and large industrial and commercial energy consumers the tools to meet all the challenges and
opportunities of the new energy environment. EMS uses real-time information and control to directly address a
broad range of requirements throughout the power delivery chain. This system offers an integrated solution to
managing new billing structures, distributed generation, energy purchasing, energy cost control, operational
efficiency, power quality and reliability.
Applications that include the meter typically require additional equipment. Display and analysis software tools
are almost always used to manage, interpret and distribute the data measured or logged by a meter. There are
usually a variety of tools used, and often these tools are connected using different communications standards
and protocols. In many cases, a meter must also provide control capabilities and device-level data sharing.
The meter can adapt to many situations. Advanced communications allow data to be shared simultaneously
across multiple networks, built-in I/O provides monitoring and control capabilities, and a variety of display and
analysis tools to help you get the most from your power system.

4 Physical Features
Prometer 100 is configurable for HV 3-phase 3-wire, HV 3-phase 4-wire or LV 3-phase 4-wire and is suitable for
mounting in a panel or on a wall. Prometer 100 has self-powered and auxiliary-powered variants. The auxiliary-
powered variant also comes with dual auxiliary support so that you can put AC or DC voltage for main and
backup supply for powering up the meter. The auxiliary circuit is not intended to be connected to the secondary
of measurement VT. For example, the VT secondary supply of 63.5 V AC (phase to neutral voltage) or 110 V
AC (phase-to-phase voltage) needs to be supplied as a voltage input to the product. Similarly three CTs, namely
R/L1, Y/L2 and B/L3, need (as applicable) to be given as a current input to the product of 1A/ 5A from
secondary side.
Note:
•Only Prometer 100-W variants can be configured as LV 3-phase 4-wire.

•In case of auxiliary-powered and self-powered variants, meter will draw power from Aux 2 supply input.
In its absence it will shift to Aux 1 supply (in case of auxiliary-powered variant) and VT supply (in case
of self-powered variant).
•Do not connect voltage transformer (VT) to any of the Aux supply input terminal as a general practice. If
it is necessary to connect VT secondary to Aux input then make sure to connect it to the Aux1 supply
only in presence of Aux 2 so that burden on measurement VT secondary can be minimal.
•Connect your reliable auxiliary supply source like DC bank/AC lighting load/ Aux power transformer etc
to Aux 2 terminal only so that meter burden will be handled by it; or take your best judgment to connect
auxiliary supply source considering the rating and suitable operation of meter and best installation
practices followed.
•The field replaceable battery can be configured to support meter reading in absence of mains power
supply depending on the requirement. It only supplies sufficient power to the meter reading and display
circuitry and will not fully power-up the meter. Contact the concern sales representative or technical
team regarding this useful feature. The battery can be replaced in the field. Take care while inserting
the battery; make sure that the polarity and fitment are correct.
•Ensure that the correct auxiliary voltage rating is used with the meter. The wrong voltage rating could
cause damage to the meter. Therefore it is recommended to verify and crosscheck the rating-plate on
the actual product in use at the site.
