1 Product overview and operating principle
Sprint 211 is a three phase, single element electricity meter that supports both Credit and Prepayment (or Pay
As You Go (PAYG) modes of operation for Smart Metering. It is available in two variants one with load control
feature and other without this feature. Please check the rating plate to know your version of the meter. The
meter supports 230V (+20%/– 20%) connection with the current of 10-100A. It is used with a Skyline-i 533/033
intimate modular communication module.
Skyline-i 533 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) and other smart metering devices via a Home Area
Network (HAN). 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 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 533/033)
It has an 1107 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.
An integrated 100A mains supply contactor is provided which can be used for disconnecting/ reconnecting
mains supply. Supply disconnection / reconnection can be done remotely over the WAN or locally. 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.
In addition, a load control switch rated at 31.5 A (variant specific) is integrated into the meter which controls
loads connected to the auxiliary load terminal of the meter.
Notes:
The operational scenario is similar for Skyline-i 033 except that the communication with IHDs over
HAN is not supported.
Some of the functionalities / features will be applicable depending upon the availability for load control
switch in the product.
