Product overview and operating principle
Premier 211 is a three phase, single element CT operated meter with fixed CT ratings. It supports credit mode
of operation for Smart Metering. The meter supports 230V (+20%/– 20%) connection with the current of 5-20A.
It has a relay of 2 Ampere and two fixed pulse outputs, one for Active Import and other for Reactive Import. It is
used with a Skyline-i 543/033 intimate modular communication module.
Skyline-i 543 communication module supports 4G (with fallback on 3G).
Skyline-i 033 communication module supports 3G (with fallback on GPRS).
The communication module sits on front belly of the meter cover. It serves as the communication gateway to the
Head End System (HES) via a Wide Area Network (WAN).
The modular communication design provides the flexibility to upgrade or change the meter’s communication
technology without the need to remove the meter or break metrological seals. The communication module
connects the meter to HES over 4G/3G. This communication provides remote data transfer between the meter
and HES either as per the request or according to the schedule. The Zigbee module connects the
communication module with other HAN devices –In Home Display (IHD).
Figure 1: Operational scenario (with Skyline-i 543/033)
It has an ANSI optical communication port for local communications and a user interface consisting of two push
buttons which allows the user to select and display the data.
Commands or changes of configuration can be delivered to the meter in the form of authorised messages or
UTRNs. UTRNs are encrypted codes that are valid only in the meter for which they are generated.
Relay disconnection / reconnection can be done remotely over the WAN or locally. A Mains frequency based
clock or a battery-backed internal clock maintains the meter’s date and time. Removal of the terminal cover and
main cover is detected and logged in power-on condition.
Internal sensors monitor external magnetic fields allowing magnetic events to be logged and reported. The
meter supports a maximum of two pulse outputs for calculating energy consumption. In addition, a 2A relay
is
integrated into the meter for demand management.
Note:
The operational scenario is similar for Skyline-i 033 except that the communication with IHDs over HAN is not
supported. For Skyline- i 033 variant, any functionality, feature or step related to IHD or HAN must be ignored
throughout the manual.
